Niskin bottle data of the Hawaii Ocean Time-series (HOT) program in the North Pacific 100 miles north of Oahu, Hawaii for cruises HOT208-217 during 2009 (NCEI Accession 0069177)
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., <150 dbar and >2000 dbar). Care was applied to ensure the highest possible accuracy and precision.
This NODC Accession contains Niskin Bottle data for HOT cruises 208-217 during 2009. CTD and thermosalinograph data from the same cruises are available in separate Accessions.
HOT 207 cruise was cut short due to a problem with the winch. No data are available.

Supplemental Information | CTD data for these HOT cruises are available in NODC accession 0068957.

Purpose | The objective of the physical component of HOT is to describe and understand the ocean climate and variability at a deep-water site in the North Pacific subtropical gyre near Hawaii. This requires a long time series of physical oceanographic variables, including water mass properties and currents,supporting and complementing the objectives of the biogeochemical component of HOT. |
