The NOAA’s Gulf of Mexico Hypoxia Watch is an interactive map interface of data from 2001 to present around the Gulf of Mexico taken from a wide range of CTD stations. Data include: dissolved oxygen concentrations and mean sea surface temperatures.
You can zoom in and out of certain areas as well as toggle the data on and off the map. This enables users to compare maps to look for patterns in where the different hypoxia zones were found year to year from 2001-present in the Gulf of Mexico.
