Low-nutrient, low-chlorophyll (LNLC) regions are aquatic zones that are low in nutrients (such as nitrogen, phosphorus, or iron) and consequently have...

High-nutrient, low-chlorophyll (HNLC) regions are regions of the ocean where the abundance of phytoplankton is low and fairly constant despite the availability...

concentration of chlorophyll. The DCM generally exists at the same depth as the nutricline, the region of the ocean where the greatest change in the nutrient concentration...

is also an essential constituent of chlorophyll. In many agricultural settings, nitrogen is the limiting nutrient for rapid growth. Like nitrogen, phosphorus...

high-nutrient, low-chlorophyll region. Iron limitation in high-nutrient, low-chlorophyll regions results in water that is rich in other nutrients because...

SCUS. Chlorophyll a is used to see the productivity of phytoplankton and therefore zooplankton. Amounts of chlorophyll-a increase with higher nutrient concentrations...

crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment. Terrestrial or aquatic plants may...

Higher levels of planktivores affect food and nutrient availability needed by other species within the lake. Low total nitrogen to total phosphorus ratios...

Eutrophication: Nutrient Sources, Composition, and Consequences. Estuaries 25:704-726. Ball, M. D., and J. F. Arthur. 1979. Planktonic chlorophyll dynamics in...

with little plant biomass (as defined by chlorophyll). The production in these high-nutrient low-chlorophyll (HNLC) waters is primarily limited by micronutrients...

present conditions. Cyanobacteria were able to adapt to this low light and thrive off the nutrient dense conditions. Green algae are a high-light adapted group...

breakdown of the sugars manufactured by chlorophyll, but in autumn, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem...

Alaska carry shelf nutrients west into the High-Nutrient, Low-Chlorophyll (HNLC) and oligotrophic (low-nutrient) waters of the northeast Pacific, or south...

chlorophyll from ocean color measurements. The cold water and high chlorophyll concentration are signatures of mixing and upwelling of cold, nutrient-rich...

within its boundaries: high chlorophyll-a concentrations in wide regions off the coast of Peru (10–15°S), high chlorophyll-a concentrations in wide regions...

winds. The low levels of nutrients in the region result in extremely low primary productivity in the ocean surface and subsequently very low flux of organic...

(deeper light penetration), low turbidity, low beam attenuation, and low concentrations of dissolved substances, chlorophyll-a, and/or total suspended solids...

the Northeast Pacific, sometimes referred to as areas of High Nutrient, Low Chlorophyll. As discussed in more detail below, dams can cause large scale...

"oligotrophic" or "hipotrophic" to describe lakes that have low primary productivity due to nutrient deficiency. (This contrasts against eutrophic lakes, which...

to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer...
