Popis
The HOT program makes repeated observations of the physics, biology and chemistry at a site approximately 100 km north of Oahu, Hawaii. 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. Samples of water column chemical analyses were collected mostly in the upper 1000m using Niskin bottles mounted on a rosette. The strategy was to sample at density horizons within the main thermocline at pressure horizons above and below this region (i.e., 2000 dbar). Care was applied to ensure the highest possible accuracy and precision. This NODC accession contains Niskin Bottle data for HOT cruises 239-248 during 2012. CTD and thermosalinograph data from the same cruises are available in separate NODC accessions. Historic data for HOT have also been archived at NODC.
