This new research helps to establish how
coastal waters influence atmospheric carbon dioxide levels and, in turn, climate.
For example, high numbers of disease - causing viruses and a bacterial species called Escherichia coli can occur in
coastal waters influenced by human wastes (e.g., sewage).

Japan, the east coast of the US, northern Brazil and south eastern Africa are also strongly
influenced by
coastal currents that transport warm tropical
waters.
This usually occurs in
coastal and estuarine areas due to reducing land - based
influence (e.g., either from reduced runoff and associated groundwater recharge, or from excessive
water withdrawals from aquifers) or increasing marine
influence (e.g., relative sea - level rise).
In addition, DOC can
influence algal blooms, phytoplankton productivity, and carbon sequestration in
coastal waters, so understanding fluxes in DOC transport into the ocean is critical for evaluating its effects on
coastal food webs.
It is likely that there has been an anthropogenic
influence on increasing extreme
coastal high
water due to an increase in mean sea level.»
These areas of open
water influence: (1) the land by allowing more ocean waves and more
coastal erosion, (2) Greenland outlet glaciers by exposing the glacier fronts to warmer ocean
waters, and (3) the atmosphere by providing a source of heat and moisture during autumn.
As discussed in the main text, however, if the large ice sheets were to begin to melt rapidly, the
influence of this
water being added to the ocean could greatly exceed all of these other effects except for self - gravitation for the vast majority of
coastal sites.
Lansner and Pepke Pedersen (2018) point out that, due to the divergent rates of warming and cooling for land vs. ocean
water, there is a significant difference in the range of temperature for the regions of the world
influenced by their close proximity to oceans and
coastal wind currents (ocean air affected, or OAA) and the inland regions of the world that are unaffected by ocean air effects and
coastal wind because they are sheltered by hills and mountains or located in valleys (ocean air sheltered, or OAS).
A wide range of human activities affect marine biodiversity both in direct ways, such as exploitation by fisheries, habitat loss due to dredging, filling, and other construction
influences, fishing gear impacts, and pollution, and in less direct ways, including effects of global change resulting in acidification, warmer
waters, and
coastal inundation.
Although eutrophication is the major concern related to these inputs, the pH of
coastal waters is also
influenced through the enhanced CO2 uptake from primary production and CO2 release from respiration associated with increased nutrient inputs.
The country thus
influences the flow of the major
water masses and results in shelf - edge currents and oceanic eddies that interact with
coastal waters over the shelf, bringing oceanic
water into the
coastal zone.
