kelp biomass #3

From Jennifer Brown:

Hi all, The SBC LTER has the satellite-based time series of kelp canopy so Margaret is the data manager (see link and abstract below). Pete Raimondi used this data set to create a time series of kelp canopy for MBNMS for the 2015 condition report.

http://sbc.lternet.edu/cgi-bin/showDataset.cgi?docid=knb-lter-sbc.54 These data are a time series of canopy biomass of the giant kelp, Macrocystis pyrifera, derived from LANDSAT 5 Thematic Mapper satellite imagery. The kelp canopy is composed of the portions of fronds floating on the surface of the water. Biomass data (wet weight, kg) are given for individual 30 x 30 meter pixels in the coastal areas extending from near Pt. Reyes, California, to Punta Abreojos, Baja California Sur, Mexico, including the Northern and Southern Channel Islands.

FYI The reason that kelp was not listed in our MBNMS species list is that we have been focused on the pelagic habitat infographic for the SDG14 product. The kelp forest habitat infographic has the kelp icons to link to kelp forest canopy data.

The other group you mentioned is PISCO, a long-term kelp forest monitoring program. They collect data on abundance of kelp, fish, and invertebrates. PISCO data from CINMS is one of the data sets that SBC MBON has been merging into one kelp forest data base. PISCO also collects data from sites throughout MBNMS. PISCO data is a target for us, but I don't think any data from the most recent years are publicly available.

Have a good weekend Jenn

Let me see if I understand, the kelp icons should be linked to http://sbc.lternet.edu/cgi-bin/showDataset.cgi?docid=knb-lter-sbc.54

In the kelp forest infographic the kelp icon is more like a large grouping of the kelp. Let me play with it to see if I can put that group layer behind the smaller icons. Is that the way it should work?
