| description | The Weddell Gyre plays a crucial role in the modification of climate by
advecting heat poleward to the Antarctic ice shelves and by regulating the
density of water masses that feed the lowest limb of the global ocean
overturning circulation. However, our understanding of Weddell Gyre water
mass properties is limited to regions of data availability, primarily along
the Prime Meridian. The aim of this paper is to provide a data set of the
upper water column properties of the entire Weddell Gyre. Objective mapping
was applied to Argo float data in order to produce spatially gridded,
time-composite maps of temperature and salinity for fixed pressure levels
ranging from 50 to 2000 dbar, as well as temperature, salinity and pressure
at the level of the sub-surface temperature maximum. While the data are
currently too limited to incorporate time into the gridded structure, the
data are extensive enough to produce maps of the entire region across three
time-composite periods (2001–2005, 2006–2009 and 2010–2013), which can be
used to determine how representative conclusions drawn from data collected
along general RV transect lines are on a gyre scale perspective. The work
presented here represents the technical prerequisite for addressing
climatological research questions in forthcoming studies. The data sets are
available in netCDF format at <a href="http://dx.doi.org/10.1594/PANGAEA.842876" target="_blank">doi:10.1594/PANGAEA.842876</a>. |
