Predictor Grids for "A Global Probabilistic Prediction of Cold Seeps and Associated Seafloor Fluid Expulsion Anomalies (SEAFLEAs)"

Predictor grids used in the analysis of "A Global Probabilistic Prediction of Cold Seeps and Associated Seafloor Fluid Expulsion Anomalies (SEAFLEAs)"

All predictor grids available in netCDF4 HDF5 file format. Grids are cell-centered sized 4320 x 2160. File names adhere to the naming conventions discussed below. The naming structure is partitioned by underscores and periods in the following order: interface to which the gridded values refer to, quantity of values contained within the grid, units and reference values/units (e.g. meters below sea level), data source, statistic calculated (if applicable), grid pitch, and file extension.

Possible interfaces from the top – down:

SS – Sea surface – atmosphere interface (may also be average of the entire water column)

SF – Seafloor – water interface (may also be denoted by GL)

GL   – Ground level (e.g. bottom of pure liquid, top of dirt)

SC – Sediment – crust interface (e.g. sediment above, igneous/metamorphic below)

CM – Crust – mantle interface (e.g. Mohorovicic discontinuity)

Units referenced are as follows:

KGM3 - kilogram per cubic meter
MS - meters per second
KM - kilometer
M_ASL - meters above sea level (i.e. meters referenced to sea level)
MWM2 - milliwatt per square meter
TGCYR - terragram of carbon per year
TGYR - terragram per year
MA - megaannum
M - meters
MGCM2 - milligram of carbon per square meter
DEG - degree
S - seconds

Statistics grids are calculated within a given radius (e.g. 10km, 50km, 125km, 250km, 500km, 1000km) of the respective cell-centered value. The statistics grids include mean (.men), average absolute deviation from the mean (.aad), and the common logarithm (.log) of the absolute value of the mean (.mlg). Additionally, some grids are a weighted count for given radii (e.g. seamounts) where weight is a cosine taper from the center of the grid cell. 

The grid pitch for this dataset is uniformly at 5-arc minute denoted by “.5m”. Additionally, the extension used (netCDF4) is denoted by “.grd”.
