Coastal upwelling has a major influence over the affected region's local climate. This effect is magnified if the ocean current is already cool. As the cold, nutrient-rich water moves upwards and the sea surface temperature gets cooler, the air immediately above it also cools down and is likely to condensate, forming sea fog and stratus clouds.
Kelp forests occur worldwide throughout temperate and polar coastal oceans. [1] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [4] Global distribution of kelp forests. "I can only compare these great aquatic forests...with the terrestrial ones in the intertropical regions. Yet if in any country a forest was ...
The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life, such as sea stars, sea urchins, and many species of coral with regional differences in ...
In response to high nutrient levels, macroalgae form dense canopies on the surface of the water, limiting the light able to reach the benthic seagrasses. [122] Algal blooms caused by eutrophication also lead to hypoxic conditions, which seagrasses are also highly susceptible to.
The density of sea water depends on the dissolved salt content as well as the temperature. Ice still floats in the oceans, otherwise they would freeze from the bottom up. The salt content lowers the freezing point by about 1.9 °C and lowers the temperature of the density maximum of water to the fresh water freezing point at 0 °C. [19]
River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts. [1][2] River ecosystems are part of larger watershed networks or catchments, where smaller headwater streams ...
Ocean surfaces occupy 72% of the Earth's total surface. They can be divided into surfaces of the relatively shallow and nutrient rich coastal areas above the continental shelves (light blue), and surfaces of the more expansive and relatively deeper but nutrient poor ocean that lies beyond (deep blue).

“Temperature has kind of a double whammy, because air temperature can change the phase of the precipitation, so more of the precipitation that falls out of the sky can actually be rain instead ...
