These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. There are multiple retrieval algorithms for estimating Chl-a. These data use the OC3 method recommended by the NASA Ocean Biology Processing Group and implemented in the SeaDAS processing software l2gen. The OC3 algorithm is described at http://oceancolor.gsfc.nasa.gov/cms/atbd/chlor_a (and links therein). {"type": "Polygon", "coordinates": [[[80.0, -60.0], [179.9, -60.0], [179.9, 10.0], [80.0, 10.0], [80.0, -60.0]]]} 80.0 179.9 -60.0 10.0 Countries | Australia Countries | Fiji Countries | Indonesia Countries | Malaysia Countries | New Caledonia Countries | New Zealand Countries | Papua New Guinea Countries | Philippines Countries | Timor-Leste Countries | Vanuatu Global / Oceans | Indian Ocean Global / Oceans | Pacific Ocean Global / Oceans | Southern Ocean Marine Features (Australia) | Bass Strait, TAS/VIC Marine Features (Australia) | Great Australian Bight, SA/WA Oceans | Ocean Chemistry | Chlorophyll Oceans | Ocean Optics | Ocean Color Regional Seas | Arafura Sea Regional Seas | Banda Sea Regional Seas | Celebes Sea Regional Seas | Coral Sea Regional Seas | Java Sea Regional Seas | Philippine Sea Regional Seas | Solomon Sea Regional Seas | Tasman Sea Regional Seas | Timor Sea States, Territories (Australia) | New South Wales States, Territories (Australia) | Northern Territory States, Territories (Australia) | Queensland States, Territories (Australia) | South Australia States, Territories (Australia) | Tasmania States, Territories (Australia) | Victoria States, Territories (Australia) | Western Australia Link to OPENDAP server documentDigital HTML Satellite Remote Sensing page on IMOS website documentDigital HTML srs_oc_snpp_chl_oc3_url/chl_oc3 documentDigital SRS - OC3 - WMS layer HTML srs_oc_snpp_chl_oc3_url documentDigital The GoGoDuck subsets and aggregates gridded data.
