The data set under this specific DOI contains data from the twelfth LOCO2 deployment (LOCO2_12), from 19 July 2015 to 2 August 2016. Data from other deployments can be found through the related identifyers.

The LOCO2 mooring was started as part of the Dutch Long-term Ocean Circulation Observations project. LOCO2 was moored in the central Irminger Sea at approximately 59.2N, 39.5W from summer 2003 until summer 2018. It was equipped with Acoustic Doppler Current Profilers for the upper ocean (<400m) and deep ocean (>2500m) circulation, a near bottom SBE37 to record the temperature and salinity of the Denmark Strait Overflow Water and (from the 10th deployment onwards) another SBE37 at around 150m. A McLane Moored Profiler (MMP) equipped with a CTD was programmed to make profiles along the mooring cable between ~150m depth and ~2400m depth.

LOCO2 was positioned in the center of the Irminger Gyre, underneath the strong atmospheric forcing of the Greenland Tip Jet, in order to study deep winter convection in the Irminger Sea.
