Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane called phycobilisomes. Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly 620 nm (depending on which specific type it is), and emits fluorescence at about 650 nm (also depending on which type it is).

Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in cyanobacteria, red algae and cryptophytes, accessory to the main chlorophyll pigments responsible for photosynthesis.The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color.

In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location (not to be confused with weathering which involves no movement).

Fluorescent Dissolved Organic Matter (fDOM)

# data[].attributes.definition
Fluorescent dissolved organic matter (FDOM) is the specific fraction of dissolved organic matter in water that absorbs light and then re-emits it as  fluorescence. It serves as a sensitive, optical proxy
used to track organic pollution, carbon cycling, and water quality in aquatic environments.

The suspended load of a flow of fluid, such as a river, is the portion of its sediment uplifted by the fluid's flow in the process of sediment transportation. It is kept suspended by the fluid's turbulence. The suspended load generally consists of smaller particles, like clay, silt, and fine sands.

Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll, found in cyanobacteria (also called blue-green algae). Because all phycobiliproteins are water-soluble, they cannot exist within the phospholipid cell membranes like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane, called phycobilisomes.
