The effects of nutrient additions to phytoplankton size structures based on chlorophyll in the Equatorial Pacific Ocean

, 2023
Phytoplankton, the primary producers of ocean, have produced over half of the oxygen in the atmosphere and use dissolved carbon dioxide to accumulate biomass which is critical to the biological pump.

Biogeochemical Markers to Identify Spatiotemporal Gradients of Phytoplankton across Estuaries

Coasts
The spatiotemporal distribution of phytoplankton in estuaries is indicative of processes and transport across the land–ocean aquatic continuum (LOAC). Estuaries, as biogeochemically and physically active systems, process large amounts of nutrients and ...

The Indian Ocean Dipole Modulates the Phytoplankton Size Structure in the Southern Tropical Indian Ocean

Remote Sensing
The phytoplankton size structure exerts a significant influence on ecological processes and biogeochemical cycles. In this study, the interannual variations in remotely sensed phytoplankton size structure in the southern Tropical Indian Ocean (TIO) and ...

Spatial and temporal trends of phytoplankton and physiochemical variables in a hypertrophic, monomictic lake [PDF]

, 2011
Spatial and temporal variations in the physical, chemical and biological composition of Lake Ōkaro were measured over 16 months. Lake Ōkaro is a small (0.32 km2) hypertrophic, monomictic lake located in the Central Volcanic Zone of the North Island, New ...

An Investigation into changes in the phytoplankton community in Loch Creran, a Scottish sea loch [PDF]

Short term and irregular sampling in Loch Creran over recent decades suggested that changes may be occurring in the phytoplankton community in the loch. This study sought to confirm this suggestion. After instigating a regular sampling regime during 2008

Factors influencing phytoplankton and dissolved oxygen in San Juan Channel: a spatial and temporal assessment

, 2011
The purpose of study was to investigate how physical and biological factors influence phytoplankton and dissolved oxygen spatially and temporally in San Juan Channel over fall and the annual cycle of 2011.

Utilizing Downwelling Irradiance for Phytoplankton Determination [PDF]

, 2012
The downwelling irradiance is rarely utilized to determine optical parameters of a water body since the ever-changing water surface induces strong signal fluctuations in the upper meters of typically 20 to 40 %.

A satellite view of the space-time variability of phytoplankton biomass in the Mediterranean Sea [PDF]

, 2010
The general thesis objective is to determine, with sufficient accuracy (i.e. using the most reliable datasets and techniques) the phytoplankton space time variability in the Mediterranean Sea (MED) using satellite data (SeaWiFS), at different timescales,

Environmental variables and plankton communities in the pelagic of lakes: enclosure experiment and comparative lake survey [PDF]

, 2005
Most primary production of lakes and oceans occurs in the well-mixed surface layer that is subject to strong seasonal and geographical variation. With increasing mixed surface layer depth average light supply and specific nutrient supply decrease and so ...
