WebDiatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule. ... Red: [chlorophyll autofluorescence] ... 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 …
Diatom - an overview ScienceDirect Topics
WebPhytoplankton live in the surface waters of the ocean, where there is usually ample light for phytoplankton to grow in the surface waters and carbon dioxide dissolved in oceans is freely available.

WebScientists use satellites to measure how much phytoplankton are growing in the ocean by observing the color of the light reflected from the shallow depths of the water. … Web1 day ago · The climatology derived from remotely sensed chlorophyll a data showed that phytoplankton blooms are usually initiated along the coast and move progressively offshore, and were separated by less than a few weeks (Fig. 5). Similarly, blooms also occurred earliest in the south and spread northward, reaching a maximum in mid-April. WebThe internal parts of the diatom cell are similar to many other types of cells so we won't go into much detail here, except for ...
