GdS2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Gd3+ is bonded in a 12-coordinate geometry to twelve equivalent S+1.50- atoms. All Gd–S bond lengths are 3.24 Å. S+1.50- is bonded to six equivalent Gd3+ and six equivalent S+1.50- atoms to form a mixture of edge, face, and corner-sharing SGd6S6 cuboctahedra. All S–S bond lengths are 2.76 Å.
CaGd2S4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (2.83 Å) and four longer (3.06 Å) Ca–S bond lengths. Gd3+ is bonded to eight equivalent S2- atoms to form a mixture of distorted face, edge, and corner-sharing GdS8 hexagonal bipyramids. There are a spread of Gd–S bond distances ranging from 2.79–3.03 Å. S2- is bonded in a 6-coordinate geometry to two equivalent Ca2+ and four equivalent Gd3+ atoms.
The presentation focused on describing a new dataset lifecycle policy that the NASA Physical Oceanography DAAC (PO.DAAC) has implemented for its new and current datasets to foster improved stewardship and consistency across its archive. The overarching goal is to implement this dataset lifecycle policy for all new GHRSST GDS2 datasets and bridge the mission statements from the GHRSST Project Office and PO.DAAC to provide the best quality SST data in a cost-effective, efficient manner, preserving its integrity so that it will be available and usable to a wide audience.
