Come Find the Data You Need!
Grow your skills and your data resources in the Data Discovery Science Competition at DataDiscoveryStudio.org
Data Discovery Studio is built to help scientists find data. It hosts records for over 1.6 million datasets and resources from over 40 repositories, and continues to grow. Individuals, classes, and sci-tech teams can compete in two categories:
(1) Build a shareable Collection of datasets from existing resources, and add links to other datasets and resources in other repositories. We show you how!
(2) Modify existing Jupyter Notebooks or create your own to explore a data type of interest. Guidance provided!
Please share broadly! We built this NSF-funded EarthCube gateway for you, want it to be useful, and eagerly welcome your feedback.
Note to coral reef scientists: the site already includes over 16,600 records of coral reef datasets and resources – enough to begin a select collection of your own to share with collaborators, and point to more.
Both competition categories contribute to science. (1) Collections will gather and tag resources, including datasets, with a focus you choose for research or community use. (2) Jupyter Notebooks will help develop workflows for datasets with a common theme or structure. Both areas will help address real science questions, share results and resources with others, and will help improve the gateway for future users. The competition is suitable for individual, team, or class entry.
DDStudio’s strongest holdings in datasets and resources are in earth, ocean, atmospheric, hydrologic, geologic, planetary, ecological, and other geoscience domains, broadly defined. Try out a favorite search term at datadiscoverystudio.org – if DDStudio doesn’t have what you need, you can contribute a new link, or point us to repositories to add. DDStudio goes beyond search: some datasets can be explored right on site using example Jupyter Notebooks (e.g., sensor data) – or develop and contribute your own Notebooks.

It has been very hard to say goodbye to the incomparable Ruth D. Gates.
Her ashes were taken aboard the Hōkūleʻa and released into Kāneʻohe Bay, Hawaiʻi in a ceremony on November 18, 2018.
If you miss her voice, as we do, the Gates Coral Lab site has links to some videos featuring Ruth and her publications. We love this one, where Ruth did a 30-min social media interview answering people’s questions. For introductory teaching and outreach we love this one, where Ruth explains corals and coral reefs in an extraordinarily accessible way.
If you wish to read them, here are links to some in memoriam articles and obituaries from multiple perspectives: The Atlantic, the University of Hawaii, The New York Times, the ARCS Foundation, and the Honolulu Civil Beat.
When asked by an audience member at a screening of Chasing Coral, “What should I do to help corals and reduce human impact on reefs?” her response was essentially: 1 – Pick Something, and 2 – Start. She believed in the power of every human being to step up and make a difference in some way, knew the diversity of talents and skills and people essential to moving forward, and through the radiance of her brilliance and passion, inspired us all to do more.
The Gates Coral Lab projects that were already in motion will continue with the students, postdocs and staff whose growth she fostered. We know we share with you this common yoke and dedication to the work of inquiry and protection for coral reefs and the planet. Those of us left behind may not have Ruth’s spectacular eloquence, insight, brilliance and spark, but we all can and must do what we are capable of doing to advocate for coral reefs, the planet, and its people.
Ruth had a vision of coral reef science as deeply collaborative, deeply integrative and multidisciplinary, and essentially multiscale. She also loved seeing scientists, managers, data and technical people working together and alongside educators, artists, and citizens for the good of coral reefs and the planet. We are all part of her collective legacy.
We’ll close with Ruth’s own words, taken from an interview posted at Paul G. Allen Philanthropies. In addition to the scientific acuity and perceptiveness of her research, Ruth’s practical and forward-looking philosophy is part of how she inspired so many.
What would you recommend we do in our daily lives to stem the loss or support the survival of corals?
We can all play a part in a solution to the problem on reefs and the solution for the planet. It really depends on what you want to do. We’re all discussing green energy, the move towards electric cars, the embracing of solar technology that is a much cleaner source to offset the burning of fossil fuels. If you’re somebody who’s politically active you could lobby your local politician to support all action that would advance an agenda that would really help protect the coral reef. Maybe you’re somebody who wants to go out and clean up a beach because everything that we take off that beach will no longer wash onto the reef and potentially damage it. Maybe you’re a boater who drops an anchor, and instead of dropping an anchor you could talk to your local managers and ask for them to put a permanent mooring in so that when you tie up your boat you don’t drag your anchor across a reef. I think what I always say to people is choose a solution that is best for you. And start doing it.
What makes you most optimistic about the work you are doing?
I’m a believer that people can pretty much do anything. Unfortunately, we seem to prefer to fix problems than to stop the problem in the first place. But we have a problem. It’s a challenge and there are many young scientists who are committed to solving the challenge of “can we save the reefs?” I’m really invigorated by the energy from the young scientists I work with. I’m invigorated by the amount of creativity that a problem of this magnitude forces in the scientific communities. I feel we can solve any problem. But to do that we have to collaborate with people that we potentially don’t usually work with. It forces us really to change the way we as scientists do business, I think. To me that’s a very exciting framework.

In a recent informal evaluation of coral reef related research articles that included simultaneous publication of code and data, by far the most popular language used was R, and RStudio is the most popular interface for working with R.
In a CRESCYNT Data Science for Coral Reefs: Data Integration and Team Science workshop held earlier this year at NCEAS, the most powerful skill introduced was using RStudio with GitHub: writing data and code to GitHub from RStudio.
Once the link is set up, the work can continue in RStudio in the way people may be familiar with, and then one can make commits to GitHub periodically to save the work and potentially pave the way for collaboration.
- Download and install R
- Download and install R Studio
- Create a GitHub account
- Connect a repository in the GitHub account to RStudio. This takes multiple steps; here are some good options to work through the process.
You can use sections of NCEAS’s long tutorial on Introduction to Open Data Science, initially developed by their Ocean Health Index group. Use the sections on overview of R and RStudio, Markdown, intro to GitHub, and skip down to collaboration in GitHub.
There are a number of other tutorials available to show how to make and use these softwares together; a beautifully clean and clear step-by-step tutorial is from Resources at GitHub; another excellent one is from Support at RStudio.
Also available to you: Hadley Wickham on Git and GitHub, a Study Group’s Version Control with RStudio and GitHub Simply Explained, R Class’s An Introduction to Git and How to Use it with RStudio, and U Chicago’s Using Git within RStudio, and Happy Git’s Connect RStudio to Git and GitHub. You may prefer the style of one of these over others.
If later you want to go further, come back for these tutorials hosted at R-Bloggers: R Blogdown Setup in GitHub, and Migrating from GitHub to GitLab with RStudio. And good news – you can now archive a snapshot of a GitHub repository to preserve and even publish a particular version of your RStudio work – plus get a doi to share – at Zenodo.
Summary: Many research scientists use RStudio as their primary analytical and visualization tool. RStudio now has the ability to connect to a GitHub repository and make commits to it from RStudio. This permits critical core functions for a simplified workbench: documenting workflows (R Markdown), preserving code and provenance, producing repeatable results, creating flexible pipelines, sharing data and code, and allowing collaboration among members of a team. Versioning and teamwork is simplified by making commits frequently and always doing fresh pulldowns prior to commit (rather than focusing on branch development). The process is valuable for individual researchers, documenting project work, and collaborating in teams.
When two major workshops concluded by the EarthCube CRESCYNT Coral Reef Science and Cyberinfrastructure Network in March 2018, there were some interesting clear outcomes in addition to the practical training and data exploration goals accomplished. The workshops were both structured around Data Science for Coral Reefs. At the end of the first, focused on Data Rescue and data management, participants decided that the most important new topic they learned about was metadata and its uses. At the end of the second, focused on Data Integration and Team Science, people had realized how essential writing good metadata was for being able to make datasets at disparate scales work together well. The metadata lessons were important emergent outcomes, and participants asked that data and metadata experts get together, use the data challenges that arose, and recommend some metadata practices and standards that would work for the coral reef community and its very broad range of data types, repositories, and pre-repository research, storage, sharing and analytical metadata needs.
We were luckily able to do exactly that with one final workshop. Through a jointly staged CRESCYNT-DDStudio workshop, we pulled together a group of metadata experts, coral reef data managers, representative scientists, and the EarthCube Data Discovery Studio’s scientists and software developers focused on metadata enhancement for finding and using data.
Special guests included Ted Habermann (Metadata 2020 project, co-author of “The influence of community recommendations on metadata completeness”; Stephen Richard (experience with schema.org and metadata standards authoring); coral reef data experts Gastil Gastil-Buhl (Moorea Coral Reef LTER), Hannah Ake (BCO-DMO), and Sarah O’Connor and Zachary Mason (NOAA NCEI’s user metadata writing interface and CoRIS), the three biggest formal repositories for coral reef research data in the US or sponsored by NSF; Eric Lingerfelt, the EarthCube Technical Officer; guests from Scripps; and DDH team members Ilya Zaslavsky, Karen Stocks, Gary Hudman, David Valentine, and Tom Whitenack with their broad and integrative metadata, software, and domain expertise. Ilya and Karen kindly hosted the group at UCSD’s San Diego Supercomputer Center and Scripps Institution of Oceanography.
Important outcomes from the workshop were mutualistic for the two projects. For CRESCYNT, they included cross-mapping an essential set of metadata (as defined by appropriate community repositories) to web standards and producing a draft ISO metadata profile for coral reef data at two levels of dataset access: (1) discovery and sharing (a simpler form with freeform text entry in many of the fields), and (2) understanding and usability at the workbench level (a more detailed form with options to supply more highly specified fields). We will finish writing these and offer them to the coral reef community for feedback and potential adoption.
For the Data Discovery Studio (formerly known as Data Discovery Hub), important outcomes included exploration of the use of the enhanced metadata at different repositories and in science use cases (including the coral reef use case), a deep dive into focusing the future trajectory of Data Discovery Studio, and some initial planning for an upcoming data science competition that will involve the coral reef data (details to be announced). Read more about DDStudio and its broader work, and be on the alert for a Data Discovery Science Competition in January 2019!
We gratefully acknowledge the generosity of our hosts, workshop travel support from NSF, the active work and engagement of our participants, and the organizations that allowed their employees time to attend and contribute to this collective effort.
Attendance is free and open to the public, online or in person.
Written while embedded in our CRESCYNT Data Science for Coral Reefs workshops. Amazingly, everyone who participated in workshop 1 – Data Science for Coral Reefs: Data Rescue – learned even more than they thought they would. We’ve had wonderful NCEAS trainers, spectacular participants with amazing datasets, and a lot of hard work over 4 days (March 7-10, 2018).
UPDATE: Here is the Data Rescue workshop agenda we used, with links to all of the training slides.
In the second intensive workshop – Data Science for Coral Reefs: Data Integration and Team Science – people will be introduced to R Studio and GitHub if they have not used them before, and then we will work on exploring techniques for integrating disparate datasets. We’ll start with a pair of datasets at a time, and efforts may involve extracting data from one dataset based on observations from another; upscaling, downscaling, resampling, or summarizing to make intervals and scales mesh – exactly the kind of process that coral reef researchers have said is a recurring challenge in asking bigger science questions.
UPDATE: Here is the Data Integration and Team Science workshop agenda we used, with links to all of those training slides and exercises.
Each workshop group is writing a paper to summarize and share lessons learned, so please stay tuned for those!
We experimented with an unusual process for these workshops: two days of training followed by two days of workathon. We’re liking it! Tell us what you think about these topics and training materials. What other workshop outputs would you like to see?
In preparation for an upcoming Data Science for Coral Reefs: Data Rescue workshop, Dr. James W. Porter of the University of Georgia spoke eloquently about his own efforts to preserve historic coral reef imagery captured in Discovery Bay, Jamaica, from as early as 1976. It’s a story from the trenches with a senior scientist’s perspective, outlining the effort and steps needed to accomplish preservation of critical data, in this case characterizing a healthy reef over 40 years ago.
Enjoy this insightful 26-min audio description, recorded on 2018-01-04.
Transcript from 2018-01-04 (lightly edited):
This is Dr. Jim Porter from the University of Georgia. I’m talking about the preservation of a data set that is at least 42 years old now and started with a photographic record that I began making in Discovery Bay, Jamaica on the north coast of Jamaica in 1976. I always believed that the information that photographs would reveal would be important specifically because I had tried other techniques of line transecting and those were very ephemeral. They were hard to relocate in exactly the same place. And in addition to that they only captured a line’s worth of data. And yet coral reefs are three dimensional and have a great deal of material on them not well captured in the linear transect. So those data were… I was very consistent about photographing from 1976 to 1986.
But eventually funding ran out and I began focusing on physiological studies. But toward the end of my career I realized that I was sitting on a gold mine. So, the first thing that’s important when considering a dataset and whether it should be preserved or not is the individual’s belief in the material. Now it’s not always necessary for the material to be your own for you to believe in it. For instance, I’m working on Tom Goreau, Sr.’s collection which I have here at the University of Georgia. I neither made it nor in any way contributed to its preservation but I’ve realized that it’s extremely important and therefore I’m going to be spending a lot of time on it. But in both cases, the photographic record from Jamaica, as well as the coral collection itself – those two activities have in common my belief in the importance of the material.
The reason that the belief in the material is so important is that the effort required to capture and preserve it is high, and you’ve got to have a belief in the material in order to take the steps to assure the QA/QC of the data you’re preserving, as well as the many hours required to put it into digital format. And believing in the material then should take another step, which is a very self-effacing review of whether you believe the material to be of real significance to others. There’s nothing wrong with memorabilia. We all keep scrapbooks and photographs that we like – things relating to friends and family, and times that made us who we are as scientists and people. However, the kind of data preservation that we’re talking about here goes beyond that – could have 50 or 100 years’ worth of utility.
Those kinds of data really do require them to be of some kind of value, and the value could either be global, regional, or possibly even local. Many local studies can be of importance in a variety of ways: the specialness of the environment, or the possibility that people will come back to that same special environment in the future. The other thing that then is number two on the list – first is belief in the material – second is you’ve got to understand that the context in which you place your data is much more important to assure its survival and utility than the specificity of the data. Numbers for their own sake are numbers. Numbers in the service of science become science. It is the context in which you place your data that will assure its future utility and preservation.
