HABs
This method used to detect harmful algal blooms should accompany remote sensing methods whenever possible to confirm species type and toxins.
What is in-situ sampling (or in-situ measurements, water testing, or animal tissue testing?)
This process can be disrupted because of high turbidity.
What is photosynthesis?
This water quality parameter is used to assess the formation of dead zones.
What is dissolved oxygen (or DO?)
This happens when there are physical, chemical, and/or biological constraints on the productivity of species and on the development of ecosystems.
What is environmental stress?
The number of water quality parameters discusses in A Comprehensive Review on Water Quality Parameters Estimation Using Remote Sensing.
What is 11?
This type of phytoplankton has a unique, small reflection peak near 650 nm that makes it possible to observe blooms using MERIS bands 6 and 7.
What are cyanobacteria?
A measurement of how light dissipates with depth in water.
What is the Diffuse Attenuation Coefficient (or Kd?)
Dissolved oxygen (DO) and this ocean parameter have a strong inverse relationship.
What is sea surface temperature (or SST?)
This index is used to study a variety of water quality parameters, including BOD.
What is the National Sanitation Foundation Water Quality Index (or NSFWQI?)
Gelbstoff
What is colored dissolved organic matter (chromophoric dissolved organic matter or CDOM?)
This method employs a simple equation to calculate the difference between satellite measured chlorophyll-a and a reference value of chlorophyll-a from a particular day.
What is an anomaly product (or anomaly method/process?)
When the total suspended solids concentration is below this level, water usually appear clear.
What is 20 mg/L?
Hypoxic waters contain less than {blank} mg/L of oxygen.
What is 2?
This satellite was used in the Akkulam-Veli Lake to study BOD.
What is IRS P6-LISS III (or IRS-P6 or IRS or Indian Remote-Sensing Satellite?)
This can be used to create two or three dimensional images of objects and can be mounted on either an aircraft or spacecraft.
What is Synthetic Aperture Radar (or SAR?)
Warming temperatures that lead to an earlier melt of sea ice is possibly linked to what shift in HAB location.
What is a northward shift of HABs in artic waters?
In 2010 and 2011, the USGS obtained discharge and turbidity measurements from this river.
What is the Toutle River?
Based on the case study, dissolved oxygen (DO) data in surface waters was retrieved from satellite-derived SST and this ocean parameter by using multiple regression analysis.
What is chlorophyll-a?
This software can be used to map the spatial variation of different water quality parameters.
What is ERDAS-Imagine (or Earth Resources Data Analysis System Imagine?)
This is a good indicator of the vertical mixing condition and water mass type and can be used to estimate primary production and phytoplankton growth rates.
What is water temperature?
