Ocean water properties near Greenland from drifting floats

OMG Ocean Water Properties Data from APEX Floats Version 1
ocean NASA POCLOUD Level 1 ASCII
In plain English

What it measures. Ocean temperature and saltiness (salinity) at different depths in the waters around Greenland, collected directly in the water.

How it's made. Gathered by autonomous APEX floats that dive and resurface on their own, using onboard sensors to record vertical profiles as part of NASA's Oceans Melting Greenland project.

How & where you'd use it. Helps scientists understand how the ocean contributes to the melting of Greenland's glaciers.

Official description

This dataset contains level 1 in situ measurements of temperature and salinity from several autonomous, profiling APEX floats. These floats change their buoyancy by inflating an external bladder with oil, allowing them to dive and surface regularly. Conductivity, Temperature and Depth sensors (CTDs) allow them to collect vertical profiles of temperature and salinity. This provided measurements of the ocean's physical characteristics around Greenland. The floats wer deployed as part of the Oceans Melting Greenland (OMG) project. The goal of the project is to find out what contributions the ocean has on Greenland's melting glaciers.
