Public Data

From APLIS07

The ALPIS 2007 field campaign was completed April 15th. Data collection by field parties started on April 1 2007. Data presented here are a limited subset of all data collected at the camp currently being processed and investigated. We plan to submit completed datasets from the camp to the National Snow and Ice Data Center at the termination of the SEDNA project for public use.

A data report will be available for download in July 2007.

Atmospheric Ozone composition

You can download a figure of ozone abundance in the air at the camp. High levels of ozone (30 - 40 parts per billion by volume) indicate background air that is not influenced by halogen chemistry. Lower ozone levels are caused by halogen chemistry associated with sea ice and indicate the conditions that deposit atmospheric mercury to the snowpack.

Weather data between April 2 and April 15

Further information on weather conditions during the SEDNA phase of APLIS 07 is available at the SEDNA website.

ADCP data collected under the command hut

These 2 plots show top 20m ocean current, in 2m bins, relative to the ice drift. To get absolute velocity, you must add camp drift to this data.
