Join us in the OceanHackWeek 2018 to explore Data Science in Oceanography!
Please join us at the OceanHackWeek 2018, August 20-24, 2018, at the University of Washington, Seattle, in collaboration with the UW eScience Institute. This 5-day hands-on workshop is aimed at exploring, creating and promoting effective computation and analysis workflows for large and complex oceanographic data. The focus will be on data provided by the National Science Foundation’s Ocean Observatories Initiative (OOI). Comparisons to other large-scale ocean observing assets, such as Argo, IOOS, etc. are welcome and encouraged.
Different from conventional conferences and workshops, the OceanHackWeek is constructed based on three core components: tutorials in data science methodologies such as data visualization and cloud computing, peer-learning, and on-site project work in a collaborative environment. We welcome all self-identified oceanographers at all career stages to apply, and hope you will join us in this exciting endeavor!
Travel and lodging grants are available for non-local accepted participants. Participants are expected to attend the entire workshop.
More information is available on: https://oceanhackweek.github.io/
To apply, please fill out the application by May 7, 2018. Accepted applicants will be notified no later than May 21, 2018.
For questions, feel free to email oceanhkw@uw.edu.

Nature Climate Change Article Highlights OOI Irminger Sea Data
Increased risk of a shutdown of ocean convection posed by warm North Atlantic summers
Marilena Oltmanns*, Johannes Karstensen and Jürgen Fischer
Abstract: A shutdown of ocean convection in the subpolar North Atlantic, triggered by enhanced melting over Greenland, is regarded as a potential transition point into a fundamentally different climate regime1,2,3. Noting that a key uncertainty for future convection resides in the relative importance of melting in summer and atmospheric forcing in winter, we investigate the extent to which summer conditions constrain convection with a comprehensive dataset, including hydrographic records that are over a decade in length from the convection regions. We find that warm and fresh summers, characterized by increased sea surface temperatures, freshwater concentrations and melting, are accompanied by reduced heat and buoyancy losses in winter, which entail a longer persistence of the freshwater near the surface and contribute to delaying convection. By shortening the time span for the convective freshwater export, the identified seasonal dynamics introduce a potentially critical threshold that is crossed when substantial amounts of freshwater from one summer are carried over into the next and accumulate. Warm and fresh summers in the Irminger Sea are followed by particularly short convection periods. We estimate that in the winter 2010–2011, after the warmest and freshest Irminger Sea summer on our record, ~40% of the surface freshwater was retained.

The OOI is pleased to announce the release of the OOI Machine-to-Machine (M2M) interface for data download.
The M2M interface provides programmatic access to OOI data and metadata via a RESTful Application Programming Interface (API). It allows authenticated users to request small amounts of data via synchronous JSON requests, request larger amounts of data in NetCDF or CSV format in order to download multiple data streams or data from multiple platforms, or set up recurring downloads to procedurally update an existing dataset. Additional commands allow for searches of the asset management system to find deployment, calibration, quality control (QC) parameters, annotations, and other information, both in bulk and for specific instruments or platforms.
Full documentation of the M2M system is underway, but there are several existing “Community Tools” resources to assist in getting started using the API. Step by step instructions and sample code are now available on the OOI Website. In addition, the OOI Data Evaluation Team will be holding instructional webinars and posting additional guides and video tutorials in the Knowledge Base in the coming months.
For additional help using the interface, if you encounter errors, or if you have suggestions, please contact the HelpDesk.
