The bottom temperature, salinity, and currents were extracted from the global HYCOM 1/12 degree output.
The current conditions are the mean bottom temperature and salinity of the past 48 hours. Overlaid arrows are the mean bottom currents during that same time period. Stratification is defined as surface values subtracted from the values at 50 meters or the bottom values if the depth is less than 50 m (e.g., bottom - surface). This gives some indication of the strength of the thermocline and halocline, which is a measure of the resistance to water column mixing due to wind and wave forcing.
The past 7-day and next 7-day forecast trends are linear slopes of those respective time periods. Any slopes that have a p-values > 0.05 are white. Overlaid arrows on the trends are the mean bottom currents during that same time period.
