Ocean temperature and salt by depth, from floats (Greenland)

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

What it measures. On-site measurements of ocean water temperature and saltiness (salinity) at different depths in the seas around Greenland.

How it's made. Collected by autonomous Alamo floats that dive and resurface by changing their buoyancy, recording vertical profiles with onboard temperature, conductivity and depth sensors.

How & where you'd use it. Gathered for the Oceans Melting Greenland project to learn how ocean water is affecting Greenland's melting glaciers, contributing to research on ice loss and sea-level rise.

Official description

This dataset contains level 1 in situ measurements of temperature and salinity from several autonomous, profiling Alamo 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.
