CTD data of the Hawaii Ocean Time-series (HOT) program in the North Pacific 100 miles north of Oahu, Hawaii for cruises HOT249-258 during 2013 (NODC Accession 0125647)

The HOT program makes repeated observations of the physics, biology and chemistry at a site approximately 100 km north of Oahu, Hawaii. The program began in 1988. Two stations are visited about once a month: Kahe Point (Station 1: 21.34N, 158.27W) and Station ALOHA (Station 2: 22.75N, 158W). Various other stations are made intermittently in support of similar research objectives or mooring deployments.

HOT CTD data are collected using a SeaBird CTD 9-11 Plus with dual sensors at the maximum sampling rate of 24 samples per second (24 Hz). They are screened for errors and processed to 2-dbar averages. Starting in 2006, the percent transmission field was replaced with a nitrate in the dataset.

This NODC Accession contains CTD data for HOT cruises 249-258 during 2013. Bottle and thermosalinograph data from the same cruises are available in separate NODC accessions, 0125579 and 0125648, respectively. Historic HOT data are also available.
