Table 2 Global environmental variables used for modelling, provided by GMED32.
Variable | Unit | Description |
|---|---|---|
Depth | m | Water depth |
Slope | degree | Slope |
Land distance | km x 100 (Euclid. Dist.) | Distance (km) to the nearest land cell (water cells only) |
Tide average | m | Tides, average of maximum amplitude. These tide model results are from a global 1/4-degree tide model which assimilated tide estimates derived from the TOPEX/Poseidon altimeter. |
Wave height | m | Height of waves in scaled discrete classes |
Wind speed | m/s | Yearly variations of the surface marine atmosphere over the global oceans (1945–1989) |
Surface current | m/s | Monthly average of zonal velocity (UVEL), meridional velocity (VVEL) values in the ocean surface. (2009–2010) |
Diffuse attenuation coefficient | 1/m | The diffuse attenuation coefficient is an indicator of water clarity. It expresses how deeply visible light in the blue to the green region of the spectrum (490 nm) penetrates into the water column. (2002–2009) |
Mean Sea Surface Temperature | °C | Mean sea surface temperature is the temperature of the water at the ocean surface. This parameter indicates the temperature of the topmost meter of the ocean water column. (2002–2009) |
Temperature range | °C | Range of sea surface temperature (2002–2009) |
Salinity surface | PSS | Salinity indicates the dissolved salt content in the ocean surface (1961–2009) |
Salinity bottom | PPT | Long term monitoring of salinity on multiple levels (1871–2008) |
Primary production | mgC·m-2·/day/cell | Proportion of annual primary production in a cell. |
ph | — | Measure of acidity in the ocean surface (1910–2007) |
