Salty brine sinking from freezing sea ice, daily

ECCO Sea-Ice Salt Plume Fluxes - Daily Mean llc90 Grid (Version 4 Release 4)
ocean NASA POCLOUD Level 4 netCDF-4
In plain English

What it measures. Daily estimates of the salty, dense brine that sinks away when seawater freezes into ice. As ice forms it squeezes out salt, and this product tracks that downward plume of extra-salty water.

How it's made. Calculated by the ECCO ocean and sea-ice model, a computer reconstruction tuned to satellite and in-water data, delivered on the model's native grid.

How & where you'd use it. A specialized input for researchers studying how freezing sea ice drives ocean mixing and deep-water formation in polar regions.

Official description

This dataset provides daily-averaged sea-ice salt plume fluxes on the native Lat-Lon-Cap 90 (LLC90) model grid from the ECCO Version 4 Release 4 (V4r4) ocean and sea-ice state estimate. Estimating the Circulation and Climate of the Ocean (ECCO) ocean and sea-ice state estimates are dynamically and kinematically-consistent reconstructions of the three-dimensional time-evolving ocean, sea-ice, and surface atmospheric states. ECCO V4r4 is a free-running solution of the 1-degree global configuration of the MIT general circulation model (MITgcm) that has been fit to observations in a least-squares sense. Observational data constraints used in V4r4 include sea surface height and model sea level anomaly (SSH) from satellite altimeters [ERS-1/2, TOPEX/Poseidon, GFO, ENVISAT, Jason-1,2,3, CryoSat-2, and SARAL/AltiKa]; sea surface temperature (SST) from satellite radiometers [AVHRR], sea surface salinity (SSS) from the Aquarius satellite radiometer/scatterometer, ocean bottom pressure (OBP) from the GRACE satellite gravimeter; sea ice concentration from satellite radiometers [SSM/I and SSMIS], and in-situ ocean temperature and salinity measured with conductivity-temperature-depth (CTD) sensors and expendable bathythermographs (XBTs) from several programs [e.g., WOCE, GO-SHIP, Argo, and others] and platforms [e.g., research vessels, gliders, moorings, ice-tethered profilers, and instrumented pinnipeds]. V4r4 covers the period 1992-01-01T12:00:00 to 2018-01-01T00:00:00.
