Front

Halocline

Back

A layer of water below the mixed surface layer where a rapid change in salinity can be measured as depth increases.

Front

Thermocline

Back

A layer between two layers of water with different temperatures.

Front

Oxygen minimum layer

Back

The layer within the ocean where the concentration of dissolved oxygen is at its lowest, typically found below the photic zone between 100m and 1000m deep.

Front

Dissolution

Back

The process of being dissolved.

Front

Run-off

Back

The flow of water from land caused by precipitation.

Front

Salinity

Back

The concentration of salts in water, typically measured in parts per thousand (ppt).

Front

Photic Zone

Back

The upper layer of the ocean where sunlight penetrates and photosynthesis occurs.

Front

Abyssal Zone

Back

The deepest part of the ocean, characterized by high pressure, low temperature, and no sunlight.

Front

Littoral Zone

Back

The nearshore area of a body of water where sunlight reaches the bottom, allowing for plant growth.

Front

Eutrophication

Back

The process by which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae.
