Exam 2 Marine science Flash cards Questions With
Complete Solutions
non-conservative constituents
(e.g., nutrients) are influenced by biological activity and have
shorter residence times.
• Biologically-important gases
Nitrogen,Oxygen,Carbon dioxide
process(es) influence solubility
Temperature,Salinity,Pressure
process(es) influence gas concentration
Temperature, Humidity,Pressure
Higher pressure or Low pressure water holds more gas
High pressure
• Compensation depth
where respiration rate equals photosynthesis rate.
Oxygen minimum zones
layer in the ocean where oxygen concentration is at its lowest,
usually between 200-1,000 meters deep.
• pH - What is it and how is it measured?
it the hydrogen ion concentration of a solution, showing how
acidic or basic it is.,
, • Carbonate buffering system
A buffering system that releases and captures hydrogen ions to
return the pH to normal
• Ocean acidification
ocean is getting more acidic which is bad for shell using animals
Major bio-limiting nutrients
Nitrogen,Phosphorus, and Silicon
• Redfield ratio - Basic idea of what it is
describes the typical nutrient composition in marine
phytoplankton.
• Importance of the ocean-atmosphere system
controls Climate,currents,solar radiation,Salt Balance,Dust
Transport
• Solar Radiation - What is the solar constant referring to and
how does it change when we incorporate the atmosphere?
The solar constant refers to the amount of solar energy received
per unit area at the top of the atmosphere. Is .4 less intense with
atmosphere.
What are angles of incidence and how do they change with
latitude?
Angles: (90- equator ,>90- Temperate,>>90-Polar)
• Global Heat Budget/Balance
mean surface temp of 16 c and regulates earth's heat
