Primary productivity in the Gulf of California, calculated from the relationship between superficial irradiance and chlorophyll in the euphotic zone

Ciencias Marinas, 1995
The vertical distribution of chlorophyll a in the Gulf of California during the spring of 1992 showed a subsurface maxima between 10 and 50 m of depth. The average surface chlorophyll concentration was 0.71 mg m–3.

Control of primary productivity and the significance of photosynthetic bacteria in a meromictic kettle lake. [PDF]

, 1989
During 1986 planktonic primary production and controlling factors were investigated in a small (A0 = 11.8 · 103 m2, Zmax = 11.5 m) meromictic kettle lake (Mittlerer Buchensee).

Effects of global climate change on chlorophyll-a concentrations in a tropical aquatic system during a cyanobacterial bloom: a microcosm study

Revista Ambiente & Água, 2017
Recent studies have investigated the impact of climate change on aquatic environments, and Chlorophyll-a (Chl-a) concentration is a quick and reliable variable for monitoring such changes.

Environmental Regulation of Photosynthetically Produced Dissolved Organic Carbon by Phytoplankton Along a Subtropical Estuarine Bay

Frontiers in Marine Science, 2022
Photosynthetically produced dissolved organic carbon (PDOC) released by marine phytoplankton has an important significance on the marine carbon cycle and on the growth of heterotopic bacteria (HB).

Organic carbon burial and their implication on sea surface primary productivity in the middle Okinawa Trough over the past 200 ka

Frontiers in Marine Science
The long-term burial of organic carbon in marginal seas plays a critical role in Earth’s carbon cycle and climate change. However, the mechanism of organic carbon (OC) burial in the Okinawa Trough (OT) during glacial-interglacial timescales remains ...

Seasonal phytoplankton and geochemical shifts in the subsurface chlorophyll maximum layer of a dimictic ferruginous lake

MicrobiologyOpen, 2022
Subsurface chlorophyll maxima layers (SCML) are ubiquitous features of stratified aquatic systems. Availability of the micronutrient iron is known to influence marine SCML, but iron has not been explored in detail as a factor in the development of ...

Spatial Variation in Primary Production in the Eastern Indian Ocean

Frontiers in Marine Science, 2021
To examine the spatial pattern and controlling factors of the primary productivity (PP) of phytoplankton in the eastern Indian Ocean (EIO), deck-incubation carbon fixation (a 14C tracer technique) and the related hydrographic properties were measured at ...
