WHOI Hawaiʻi Ocean Time-series Site (WHOTS)

whots_main_sm

The Woods Hole Oceanographic Institution (WHOI) Hawaiʻi Ocean Time-series Site (WHOTS) is located 100 km north of the island of Oʻahu. WHOTS is part of the Hawaiʻi Ocean Time-series (HOT) program that has been active since 1988. Repeated biological, chemical, hydrographic, and physical observations have been taken at this site in order to create a valuable time series dataset. More information and data can be found at the WHOTS website.

The entire carbon dioxide (CO2) time series for the WHOTS buoy is shown below. For closer inspection of the dataset, simply slide the striped black markers on the bottom right and left of the graph to narrow the time range. The CO2 for the air and sea water are in molar fractions (µmol/mol), meaning it is the molar amount that CO2 accounts for out of the total substance.
