WebA phytoplankton bloom occurred in Ardley Cove, King George Island in January 2016, during which maximum chlorophyll-a reached 9.87 mg/m3. Records show that blooms have previously not occurred in this area prior to 2010 and the average chlorophyll-a concentration between 1991 and 2009 was less than 2 mg/m3. Given the lack of in situ … Webphytoplankton biomass. However, diatom and dinoflagellate biomass does not correlate strongly with chlorophyll either, suggesting that other groups of phytoplankton are a major constituent of the surface primary producers. The presence of the cyanobacterium Trichodesmium was noted at all sites, supporting this hypothesis.
WebDec 15, 2024 · The spectral characterization of the wobbling photoresponse shows a well-defined maximum for wavelengths in the band λ ~ 450 to 490 nm , which is a prevalent waveband that diatoms have adapted to absorb using pigments such as chlorophyll c2, c3, and fucoxanthin .

Like land plants, …
WebAll diatoms contain chlorophylls a and c2. Chlorophylls c1 and c3 may also be present; however, chlorophyll b is never found in diatoms. Although the coloration of diatoms varies, living diatoms are frequently brown due to the presence of the accessory pigment fucoxanthin, which masks the green coloration of the chlorophylls.
