About the Arctic Shipborne Sea Ice Standardization Tool (ASSIST)
ASSIST is a multi-media data collection tool that supports standardization of observation methods throughout the Arctic Ocean. Observers on vessels from multiple nations are using ASSIST to report near real-time visual sea ice observations.
This observation method follows the WMO (1970) convention to be compatible with previous protocols (including Egg Code, ASPeCt, Canadian MANICE) with special attention to characterizing Arctic specific conditions, including surface melt conditions, sediment and ice algae.
Ice Watch is an international, collaborative program to coordinate Arctic-wide visual sea ice observations collected from ships operating in ice-covered seas of the northern hemisphere, with resources to:
- record ship based sea ice observations using the Arctic Shipborne Sea Ice Standardization Tool (ASSIST) software
- access data collected on current cruises using
- archive and retrieve past observations
Download data: You don't need an account to download data. The data archive is hosted by the Geographic Information Network of Alaska (GINA).
ASSIST software has been developed to help you collect and archive data. You will need a Google account to register, log in, download ASSIST, and upload your data. Once you’re logged in, you can:
- Download ASSIST
- Download observation sheets and codes
- Create and manage cruise datasets
- Upload and manage observations
- to link to our database
- to use ASSIST in your own data collection
- if you have old Ice Watch data that is not in the ASSIST format
