Introduction

Factors Responsible for Variations in Ocean Salinity

7 words

Main Body

1Precipitation: High rainfall causes dilution of salt and thus salinity falls.

2Evaporation spread: High evaporation leads to more salinity as water precipitates leaving behind salt.

3Continental landmass → Enclosed by continents: Caspian sea & Mediterranean sea enclosed by continent have greater salinity.

6Aeolian Dynamics: Impacts of upwelling & downwelling of seawater affect salinity.

Navigation: Ships & cruise have limitations in their capacity based on ocean current movement. Movement occurs from low salinity to high salinity areas.

Tourism: Impact maximum in trade areas based on ocean salinity.

Biodiversity: Fishing impact due to fish availability affected by salinity variations. High salinity impacts fish populations.

Coral: Coral bleaching caused by high salinity.

Mangroves: Impacted due to high salinity variations.

Geographical impacts:

Ocean Current: Movement occurs from low salinity to high salinity areas, affecting circulation patterns.

Local climate & weather patterns: May change due to salinity variations.
