James Porter’s coral photo monitoring project in Discovery Bay

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.

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.

Where: NCEAS, Santa Barbara, CA

Workshop description:

This workshop is recommended for early to mid-career and senior scientists with interest in applying technical skills to collaborative research questions and committed to subsequently sharing what they learn. Participants will learn how to structure and combine heterogeneous data sets relevant to coral reef scientists in a collaborative way. Topics covered on days 1 and 2 of the workshop will cover reproducible workflows using R/RStudio and RMarkdown, collaborative coding with GitHub, strategies for team research, data modeling and data wrangling, and advanced data integration and visualization tools. Participants will also spend 2 days working in small teams to integrate various coral reef datasets to practice the skills learned and develop workflows for data tidying and integration.

The workshop is limited to 20 participants. We encourage you to apply via this form. Workshop costs will be covered with support from NSF EarthCubeCRESCYNT RCN. We anticipate widely sharing workshop outcomes, including workflows and recommendations. Anticipate some significant pre-workshop prep effort.

We’re extremely pleased to be able to offer two workshops in March 2018 at NCEAS. The first is CRESCYNT Data Science for Coral Reefs Workshop 1: Data Rescue. Apply here.

When: March 7-10, 2018
Where: NCEAS, Santa Barbara, California, USA

Workshop description:

Recommended for senior scientists with rich “dark” data on coral reefs that needs to be harvested and made accessible in an open repository. Students or staff working with senior scientists are also encouraged to apply. Topics covered on days 1 and 2 of the workshop will cover the basic principles of data archiving and data repositories, including Darwin Core and EML metadata formats, how to write good metadata, how to archive data on the KNB data repository and elsewhere, data preservation workflow and best practices, and how to improve data discoverability and reusability. Additionally, participants will spend approximately 2 days working in pairs to archive their own data using these principles, so applying with a team member from your research group is highly recommended.

The workshop is limited to 20 participants. We encourage you to apply via this form. Workshop costs will be covered with support from NSF EarthCubeCRESCYNT RCN. Participants will publish data during the workshop process, and we anticipate widely sharing workshop outcomes, including workflows and recommendations. Because coral reef science embodies a wide range of data types (spreadsheets, images, videos, field notes, large ‘omics text files, etc.), anticipate some significant pre-workshop prep effort.

CRESCYNT Toolbox – Discovery of Online Datasets

cinergi-coralscreendump
Data discovery at cinergi.sdsc.edu

Announcing recent progress for data discovery in support of coral reef research!

Take advantage of this valuable community resource: a data discovery search engine with a special nose for locating coral reef research data sources: cinergi.sdsc.edu.

A major way CRESCYNT has made progress is by serving as a collective coral reef use case for EarthCube groups that are building great new software tools. One of those is a project called CINERGI. It registers resources – especially online repositories and individual online datasets, plus documents and software tools – and then enriches the descriptors to make the resources more searchable. The datasets themselves stay in place: a record of the dataset’s location and description are registered and augmented for better find and filter. Registered datasets and other resources, of course, keep whatever access and use license their authors have given them.

CINERGI already has over a million data sources registered, and over 11,000 of these are specifically coral reef datasets and data repositories. The interface now also features a geoportal to support spatial search options.

The CINERGI search tool is now able to incorporate ANY online resources you wish, so if you don’t find your favorite resources or want to connect your own publications, data, data products, software, code, and other resources, please contribute. If it’s a coral-related resource, be sure to include the word “coral” somewhere in your title or description so it can be retrieved that way later as well. (Great retrieval starts with great metadata!)

To add new resources: Go to cinergi.sdsc.edu, and click on CONTRIBUTE. Fill in ESPECIALLY the first fields – title, description, and URL – then as much of the rest as you can.

Try it out!

Thanks to EarthCube, the CINERGI Data Discovery Hub, and the great crew at the San Diego Supercomputer Center and partners for making this valuable tool possible for coral reef research and other geoscience communities. Here are slides and a video to learn more.

CRESCYNT Toolbox – Data Repositories – Estate Planning for your Data

“Hypotheses come and go but data remain.”    – Ramon y Cajal

Taking care of our data for the long term is not just good practice, allowing us to share our data, defend our work, reassess conclusions, collaborate with colleagues, and examine broader scales of space and time – it’s also estate planning for our data, and a primary way of communicating with future scientists and managers.

Here are some great options for long-term data storage, highlighting repositories friendly to coral reef science.

First, there are some important repository networks useful for coral reef data – these can unify standards and offer collective search portals: we like DataONE (members here) and bioCaddie (members here).

KNB – the Knowledge Network for Biocomplexity offers open and private data uploads; ecological orientation. DataONE network.

NOAA CoRIS: Coral Reef Information System – often free to use and can accept coral reef related data beyond NOAA’s own data; contact them first.

BCO-DMO – Biological and Chemical Oceanography Data Management Office – if you have an NSF grant that requires data storage here, you’re fortunate. Good data management guidelines and metadata templates, excellent support staff. Now a DataONE member.

Dataverse – supported by Harvard endowments. There are multiple organizational dataverses – the Harvard Dataverse is free to use. bioCaddie member.

Zenodo – free to use, supported by the European Commission (this is a small slice of CERN’s enormous repository for the Large Hadron Collider). Assigns dois. We invite you to include the “Coral Reef” community when you upload. bioCaddie member.

NCBI – the National Center for Biotechnology Information is very broadly accepted for ‘omics data of all types. A bioCaddie member.

DataCite – not a repository, but if you upload a dataset at a repository that does not assign its own doi’s, you can get one at DataCite and include it when publishing your datasets.

We’ve not listed more costly repositories such as Dryad (focused on journal requirements) or repositories restricted to institutions. What about other storage options such as GitHub, Amazon Web Services, websites? Those have important uses, but are not curated repositories with long-term funding streams, so are not the best data legacy options.

eggs-stacked-imagesMost of these repositories allow either private (closed) or public (open) access, or later conversion to open access. Some have API’s for automated access within workflows. These are repositories we really like for storing and accessing coral reef work. Share your favorite long-term data repository – or experiences with any of the repositories listed here – in the comments.
