Water Temperature

​
​
This map displays the changes in water temperature across the HRE. There is a clear pattern of warming temperatures over the course of the summer with the most inland regions being the warmest.
Changes in salinity throughout the HRE, cooler colors represent lower salinity levels while warmer colors represent higher salt levels. Areas with lower salinity are a likely result on freshwater input sources.
Salinity
Dissolved Oxygen
Dissolved oxygen relates to the amount of oxygen present in the water. This map indicates uneven distribution of oxygen within the HRE and clear low-oxygen areas at the heads of the estuary systems.​ Areas of low oxygen saturation lead to deadly hypoxic conditions.
Chlorophyll Fluorescence
Chlorophyll is found in photosynthetic organisms and can be used to determine relative abundance of phytoplankton. This map indicates an uneven distribution of photosynthetic organisms with varying abundance.
Chlorophyll Fluorescence v. Water Temperature
The correlation between water temperature and chlorophyll fluorescence refined by location. Each color represents a different location.​
