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. This dataset also includes physical-biogeochemical measurements from Station HALE-ALOHA (Hawai'i Air-sea Logging Experiment, A Long-Term Oligotrophic Habitat Assessment), measurements of high-quality air-sea fluxes and the associated upper ocean response from The Woods Hole Oceanographic Institution (WHOI) Hawaii Ocean Timeseries (HOT) Site (WHOTS), as well as hydrographic and biogeochemical parameters from the ALOHA-CLIMAX Regional Study. To describe and understand the ocean climate and variability at a deep-water site in the North Pacific subtropical gyre near Hawaii. Hawaii Ocean Time-series (HOT) was initiated and funded through grants from the National Science Foundation under the auspices of the Joint Global Ocean Flux Study (JGOFS) and the World Ocean Circulation Experiment (WOCE). The field phase of these programs has ended, but support from the Ocean Sciences Division of NSF has enabled continuation of our basic HOT measurement program. The physical oceanographic component contributes to the objectives of the World Climate Research Programme (WCRP) Climate Variability and Predictability (CLIVAR) Programme by providing information on interannual to decadal variability of the North Pacific Ocean. The US CLIVAR Office funded the physical oceanographic data during 2008. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:Station-ALOHA-HOT Preview graphic PNG 0000497 0000639 0000640 0000641 0001016 0001704 0001707 0001710 0010624 0010740 0011142 0041594 0041849 0042029 0046427 0048660 0048725 0048896 0059842 0059936 0059943 0068957 0069177 0069501 0087584 0087596 0087988 0088839 0089168 0101146 0101727 0103907 0119430 0119895 0120323 0125579 0125647 0125648 0140225 0218247 0224688 0224752 0224756 0224849 0242075 0276338 0284084 0298064 0308400 9300009 9300040 9300148 9300149 9300183 9700176 9800125 9900206 9900207 9900208 9900212 9900213 9900214 9900215 NCEI ACCESSION NUMBER 2000-01-12 publication AIR TEMPERATURE AIR TEMPERATURE - DRY BULB AIR TEMPERATURE - WET BULB AMMONIA (NH3) AMMONIUM (NH4) bacteria BACTERIA - HETEROTROPHIC BAROMETRIC PRESSURE BIOCHEMISTRY biological data CARBON CARBON - TOTAL ORGANIC CARBON ASSIMILATION CAROTENOIDS - PLANT CHLOROPHYLL CHLOROPHYLL - RELATIVE FLUORESCENCE CHLOROPHYLL A CHLOROPHYLL C cloud amount/frequency cloud type CONDUCTIVITY CURRENT DIRECTION CURRENT METER - EAST-WEST COMPONENT (U) CURRENT METER - NORTH-SOUTH COMPONENT (V) CURRENT SPEED CURRENT SPEED - UP/DOWN COMPONENT (W) DELTA CARBON-13 DELTA NITROGEN-15 DEPTH - OBSERVATION dew point Diadinoxanthin DISSOLVED INORGANIC CARBON (DIC) DISSOLVED ORGANIC CARBON Dissolved Organic Nitrogen DISSOLVED OXYGEN DOWNWELLING RADIANCE DYNAMIC DEPTH ANOMALY DYNAMIC HEIGHT Eukaryote FLUORESCENCE fucoxanthin HPLC PIGMENTS HYDROCARBONS - TOTAL RESOLVED HYDROSTATIC PRESSURE irradiance LIGHT ATTENUATION LIGHT TRANSMISSION NITRATE nitrate + nitrite content (concentration) NITRATE/NITRITE RATIO NITRITE NITROGEN NITROGEN - PARTICULATE nitrous oxide (N2O) NUTRIENTS ORGANIC CHEMICALS OXYGEN OXYGEN - DISSOLVED ORGANIC partial pressure of carbon dioxide - water Particulate Inorganic Carbon PARTICULATE ORGANIC CARBON PARTICULATE ORGANIC NITROGEN (PON) particulate phosphorus pH PHAEOPIGMENTS phosphate PHOSPHATE - TOTAL PHOSPHORUS - ORGANIC PHOTOSYNTHETIC ACTIVE RADIATION (PAR) PHYTOPLANKTON PIGMENTS POLYCHLORINATED BIPHENYLS Potential temperature (theta) PRIMARY PRODUCTIVITY Prochlorococcus SALINITY SALINITY - SURFACE WATER SEA STATE SEA SURFACE TEMPERATURE Secchi depth SIGMA-T SIGMA-THETA silica silicate SOLAR RADIATION - ATMOSPHERIC SOUND VELOCITY surface irradiance per incubation period suspended solids Synechococcus TIDE HEIGHT TIDE STAGE total alkalinity TOTAL CARBON TOTAL PHOSPHORUS TRANSMISSIVITY turbidity UPWELLING IRRADIANCE UREA VISIBILITY Volatile Organic Compounds WATER COLOR WATER DENSITY water depth WATER TEMPERATURE WAVE DATA WAVE HEIGHT WAVE PERIOD WEATHER WIND DIRECTION WIND FORCE WIND SPEED ZOOPLANKTON BIOMASS theme NODC DATA TYPES THESAURUS bathythermograph - XBT bottle buoy - moored buoy carbon-14 incubation CTD fluorometer inverted echo sounder (IES) irradiance detector laboratory analysis meteorological sensor oxygen sensor radiometer salinometer Secchi disk sediment sampler - corer sediment sampler - grab spectrophotometer thermistor thermosalinograph transmissometer trap - sediment visual analysis instrument NODC INSTRUMENT TYPES THESAURUS benthic biological chemical current measurements geological integrated profiles laboratory analyses meteorological optical physical profile site samples time series underway water chemistry theme NODC OBSERVATION TYPES THESAURUS CROMWELL FIXED PLATFORM OF UNITED STATES FIXED STATIONS OF UNITED STATES KA'IMIKAI-O-KANALOA KAHO KAIMALINO KILA MARINE VIEW MOANA WAVE NA'INA NESHANIC NEW HORIZON NOAA Ship Hi'ialakai NOAA Ship Oscar Elton Sette NOAA Ship Townsend Cromwell OCEANUS R/V KILO MOANA R/V Knorr R/V MAURICE EWING R/V Melville R/V Roger Revelle R/V THOMAS G.

The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity.
