New Sea Ice Pressure Ridge Sail Height Product Available

Oct 10, 2019

sea ice pressure ridge sail heightA 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.

New sea ice datasets added to PolarWatch

Apr 25, 2019

nsidc sea ice preview interfaceThe 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

Feb 21, 2019

soccom float mapSouthern 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

Dec 19, 2018

Farrell_AGU_2018_Poster_Ice_graphicPolarWatch 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

Sep 24, 2018

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.
