PolarWatch News and Events
New Sea Ice Pressure Ridge Sail Height Product Available
A new Sea Ice Pressure Ridge Sail Height product from NOAA is now available in the PolarWatch ERDDAP. Sail height data is derived from high-resolution airborne imagery acquired during NASA's annual Operation IceBridge campaigns in the Arctic (2010-2018). Pressure ridges impact mass, energy, and momentum budgets of sea-ice cover and present an obstacle to transportation through icy waters. Quantifying ridge characteristics is important for understanding total sea-ice mass and for improving sea-ice dynamics in high-resolution models.
Seminar on Arctic Sea Ice Altimetry
On September 11, PolarWatch program scientist, Sinéad Farrell, presented, "Advances in Satellite and Airborne Altimetry over Arctic Sea Ice – Towards Improved Prediction", as part of the NOAA NESDIS STAR seminar series. The seminar abstract and slides are available on the seminar series web page.
New Marine Heatwave Emerges off West Coast, Resembles "the Blob"
Researchers are monitoring a new marine heatwave off the West Coast for effects on the marine ecosystem. The warm expanse building off the West Coast stretches roughly from Alaska south to California
Slides are now available from the recent webinar Jennifer Sevadjian presented as part of the NESDIS STAR webinar series. The slides provide an overview of the data and services provided by PolarWatch and highlight available user training materials and training courses.
ERDDAP Webinar - Easy data access and visualization
Cara Wilson recently presented a NESDIS STAR webinar entitled, "Easy data access and visualization using the ERDDAP data server". The webinar slides are now available online.
New sea ice datasets added to PolarWatch
The NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 3 and the near real-time version of the Climate Data Record datasets have been added to the PolarWatch catalog. These datasets provide long term science quality sea ice concentration records for the Arctic and Antarctic dating back to 1978.
SOCCOM Near-Realtime BGC-Argo data now on PW ERDDAP
Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) BGC-Argo float data is now available on the PolarWatch ERDDAP. The SOCCOM project augments conventional Argo floats with biogeochemical sensors to measure carbon (pH), nutrients (nitrate), and oxygen. About 200 autonomous floats provide coverage over the Southern Ocean, with vertical coverage deep into the water column.
Visualizing a Decade of Change in the Arctic Sea Ice Cover AGU iPoster
PolarWatch scientist Sinéad Farrell delivered an interactive poster on visualizing change in Arctic sea ice cover at AGU 2018. The poster highlights NOAA Lab for Satellite Altimetry sea ice data products showing variability in ice type and ice thickness over the last decade and shows some very early ICEsat-2 results.
Spring Satellite Data Workshop in Juneau
The next NOAA Ocean Satellite Data Course will be held in Juneau, Alaska, March 5-7, 2019. In this annual three-day course participants learn about ocean satellite data and how to easily obtain it. Participants gain hands on experience working with data of interest to them. The course provides scientists who are not regular users of satellite data with the tools they need to incorporate satellite data into their projects.
Preview Datasets in Polar Projection
We've added new data previewing capability to the PolarWatch Data Catalog. All datasets can now be viewed in polar projections and quick previews of the data are available for any time stamp over the length of record.
2017 Arctic Report Card Released
The Arctic Report Card (www.arctic.noaa.gov/Report-Card/), going into its 12th year, considers a range of environmental observations throughout the Arctic, and is updated annually. As in previous years, the 2017 update highlights the changes that continue to occur in, and among, the physical and biological components of the Arctic environmental system.
Program Scientist interviewed about Warming Arctic on Today Show
PolarWatch sea ice expert, Sinead Farrell was featured last week on a Today Show segment about warming Arctic temperatures. Watch the 3-minute video clip on the Today Show website.
New Data Catalog Interface Release
A new release of the PolarWatch data catalog provides an improved search and filter interface, data download access to all datasets in the PolarWatch catalog and critical infrastructure improvements.
New VIIRS ocean color datasets
Data Catalog Prototype Released
A new interface to find, preview and download polar satellite data is now available. The interface will remain in development through 2018. Let us know if you see ways it could be improved to help you in your work.
New Data Access Example
Check out our new code example that shows how to use python to access data from the PolarWatch ERDDAP data server and make a polar projected plot.
Satellite Data Training
Register for the 2017 NOAA Ocean Satellite Data Course in Seattle, WA. It will be held Aug 22-24 and is an opportunity to learn how to incorporate satellite data into your projects and get hands on training from experts.
