But there's more for «Mission to Earth» geeks (I count myself as one) over at the Earth Observatory Web site, where SeaWiFS merits the «Image of the Day» — a view of Earth showing the averaged chlorophyll concentration in the oceans from 1998 through 2010 (and of course showing all that glorious green terrestrial plant life, too):
The euphotic zone was calculated from the mean surface chlorophyll concentrations using the Case I model of Morel and Berthon (1989), while the export depth was calculated by subtracting the euphotic zone depth from the water depth.
«But what we do see in the analysis of the data is an increase in temperatures and chlorophyll concentration across the bay and a changing relationship between nitrogen and chlorophyll — an indicator of algae growth and water quality — as those waters warm.»
But Lee thinks their feces may have some influence, since chlorophyll concentrations, signaling more algal growth, doubled after adding only 0.5 g of feces to the microcosms.
The nutrient - rich water helps stimulate phytoplankton blooms, whose chlorophyll concentrations yield the colored swirls.
Waters with high chlorophyll concentrations appear light blue to yellow, indicating the abundance of phytoplankton.
Because of weak inputs of nutrients in the surface mixed layer, chlorophyll concentration always remains low in the subtropical gyres.
Regionally, positive correlations between chlorophyll a concentrations and both dissolved CH4 concentrations (Indian reservoirs; Narvenkar et al. 2013) and CH4 fluxes (north temperate lakes; West et al. 2015a) have been found in lakes and reservoirs.
Multiple scattering computations show that these models are capable of reproducing realistic underwater light albedos for wavelengths ranging from 400 to 600 nm, and for chlorophyll a concentrations ranging from 0.03 to 3.0 mg / m3.
Nutrient concentrations are higher along the Gulf Stream path in response to the shallower isopycnals and have contributed to the enhanced chlorophyll concentrations around the Gulf Stream path.
Similarly, the buoy anchors lines could be equipped with instrumentation to collect data on ocean currents, temperature or chlorophyll concentrations at different depths.
The effect of stress level on needle length was significant, but not the effect on needle chlorophyll concentration (Table 2).
