#TITLE: 
Water Column Chemical Data of the Hawaii Ocean Time-series (HOT) program 
in the North Pacific 100 Miles North of Oahu, Hawaii for Cruises 
HOT199-227 during 2008-2010

#PROJECT: 
HOT/JGOFS
Biogeochemistry and Ecology Component (BEACH) of the Hawaii Ocean Time-series (HOT) 
Joint Global Ocean Flux Study (JGOFS)

HOT was initiated and funded through grants from the National Science 
Foundation (NSF) 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. State of Hawaii general funds also support HOT.

#ABSTRACT:
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.  A total 56 parameters are acquired.

This NODC Accession contains Water Column Chemical data for HOT cruises 
199-227 during 2008-2010.  These data represent the full array of 
chemical parameters in support of the JGOFS program, and for convenience,
a repeat of key parameters found in the Bottle and CTD Data as prepared by the 
Physical Oceanographic (PO) component of HOT, which are also archived at NODC.  
NODC holds historic Water Column Chemical data for HOT cruises 1-198 in
separate accessions.

Cruise 207 was cut short due to a problem with the winch and no data are available.  
Cruise 218 was a short cruise due to equipment problems and only has one ctd cast 
and no thermosalinograph data.

#PURPOSE: 
The objective is to support studies of the earth as a system of interrelated
physical, chemical, and biological processes that act together to regulate
the habitability of our plantet.  The first goal is to understand the earth-
ocean-atmosphere system and how it functions.  The second goal is to
describe, and eventually predict, major cause-and-effect relationships.
The former goal is focused on physical oceanographic processes and the
latter on biogeochemical proceses.

The Biogeochemistry and Ecology Component (BEACH) of the Hawaii Ocean 
Time-series (HOT) aims to document and understand seasonal and interannual 
variability in the rates of primary productivity, new production and particle
export from the surface ocean.  Also it seeks to determine the mechanisms and
rates of nutrient input and recycling, especially for nitrogen and phosphorus
in the upper 200 m of the water column.  Another goal is to measure the 
time-varying concentrations of dissolved inorganic carbon in the upper
water column and estimate the annual air-to-sea CO2 flux.

#METHODOLOGY:
Generalities are given below.  Please see REFERENCES for additional
information. 

Each of the (approximately monthly) HOT cruises follows the same basic
pattern with some flexibility for ancillary projects to be done after the
core sampling has been completed. During transit from Honolulu to the
time-series station ALOHA (A Long-term Oligotrophic Habitat Assessment) one
weight test is done to between 700 and 1000 m at station 1 off Kahe Point
(16 km offshore from the western tip of Oahu, 21 20.6' N, 158 16.4' W,
1500 m water depth). Following the successful winch test, a CTD/rosette cast
to 1000 m is conducted. This cast serves as a "shakedown" for the remainder
of the cruise, and the functioning of the components of the CTD/rosette
system as well as coordination between winch, deck and console operators can
be tested. The training of new personnel in activities such as taking
meteorological observations, and sampling salinities is also done in this
station. The data taken at Kahe Point (station 1) represent an additional
time-series of water properties at a near-shore site.
 
Upon arrival at ALOHA (station 2), operations commence with a deep cast
(maximum depth approximately 4750 m), 36-hour burst sampling3 of the upper
1000 m at the same location, plus CTD casts to support ancillary JGOFS work
of about an extra 12 hours duration. Time permitting, the last CTD cast of
the cruise will be a deep cast. On occasion, one cast will be done at
station 3 (40 miles north of ALOHA at 23 25' N, 158 W).

The second and following casts at station ALOHA are sampled to at least 1000
m depth. Cast 2 is called a "density cast" because water samples are taken
at a number of specified density values ranging from [sigma-theta]= 27.37 to
the surface with the intent to resolve the profiles of salinity, dissolved
oxygen, and nutrients in potential density coordinates Depths sampled during 
the following casts within the 36-hour burst sampling period are chosen both 
by the JGOFS group and the WOCE team, who have to ensure that at least one 
water sample each is taken within the mixed layer, the shallow salinity 
maximum, the intermediate salinity minimum and the deepest position of 
the rosette for calibration of the CTD conductivity sensor. If oxygen 
bottles will be taken from the cast, then the sampling should include 
at least the mixed layer, oxygen maximum, oxygen minimum and the deepest 
rosette position for calibration of the CTD oxygen sensor. The second 
deep cast of the cruise (if there is one) should include sampling of 
oxygen bottles in at least seven levels appropriate for calibration of 
the CTD oxygen sensor, i.e. in the oxycline and two more levels below 
the oxygen minimum, in addition to the four levels mentioned before.

Water samples are collected during HOT cruises using a 24 place
rosette. Samples of salinity, oxygen, phosphate, nitrate and
silicate are regularly taken from both shallow and deep water casts.
Salinity samples are taken back to the University of Hawaii where
they are measured using an Autosal salinometer . Phosphate, nitrate
and silicate samples are also measured at the University of Hawaii
while oxygen measurements are conducted aboard ship during the
cruises.

The primary objective of the HOT program is to assess variability in the
central Pacific Ocean on annual and interannual time scales. One of our most
important concerns, therefore, is to ensure that the highest possible
precision and accuracy is consistently maintained for all water column
chemical measurements. In order to achieve the highest possible data
quality, we have instituted a quality-assurance/quality-control program,
and have attempted to collect all ancillary information necessary to
ensure that our data are not biased by sampling artifacts.

Because sampling is over 36 hours, one can average out the effects
short-term changes of the depth of density surfaces and the magnitude of
hydrographic and nutrient variables (inertial, tidal, and shorter periods).

It should also be noted that both DOC and pH analytical protocols
have changed causing offsets in the the temporal data sets.  The DOC
protocol changed from the persulfate oxidation (HOT 1-27) to the
high-temperature platinum catalyzed oxidation (HOT 44- present).  The
pH was intially analyzed by the electrode method and calibrated against
NBS scale (HOT 23-32), during 1992 the pH was analyzed by the
spectrophotometric method and the pH calculated on the "total scale"
and converted to the "seawater scale" (HOT 36-present).

Analytical procedures are summarized below.  See REFERENCES for more

#INSTRUMENT TYPES:
i) CTD

The underwater CTD hardware consists of a main pressure housing containing
power supplies, acquisition electronics, telemetry circuitry, and a pressure
transducer. This system has the ability to acquire various channels of data
at the rate of 24 scans per second. It has five frequency encoded channels
for two temperature, two conductivity and one pressure sensors, and eight
A/D channels for oxygen sensors, fluorometer and altimeter. The suite of
modular sensors is attached externally. The three primary sensors used
during WOCE/JGOFS work are a temperature sensor, a conductivity sensor for
measuring salinity, and a dissolved oxygen sensor. An underwater pump is
connected to the temperature sensor and conductivity cell via a tc-duct,
which then connects to the oxygen sensor to provide rapid and constant flow
of water past the sensors. The Sea-Bird 9/11 Plus system provides us with a
redundant set of temperature, conductivity and oxygen sensors connected to
another pump. In addition we have the ability to measure natural
fluorescence using a Sea-Tech Flash Fluorometer. For deep casts a Datasonics
programmable sonar altimeter (Model PSA-900) is connected to the CTD. 

ii) SeaBird Carousel
 
The SeaBird carousel is an electro-mechanical device that uses a magnetic
trigger to trip Niskin bottles upon command. This is accomplished when the
release device inside the carousel housing receives a signal from the
SeaBird deck box, which causes it to advance one position per command. This
in turn releases the lanyard for a specific Niskin bottle, assuming the
bottles were cocked beforehand.
 
iii) Niskin bottles
 
It is part of the pre-cruise preparations to log the rosette configuration
which matches Niskin bottles with rosette position. An update of this
information should be done in the Science Log if the Niskin bottles are
changed for any reason. Note that the rigging of Niskin lanyards and
inspection of Niskin bottles requires considerable experience to be done
properly.

Water samples were collected using a 24-place aluminum rosette manufactured
by Scripps Institution of Oceanography's Oceanographic Data Facility (ODF).
Twelve-liter polyvinylchloride sampling bottles, also made by ODF, were used
on this rosette. These sample bottles were equipped with Buna-N rubber
O-rings, teflon-coated steel springs and standard General Oceanics samping
valves.

    BEACH water column chemical data are distributed as ASCII flat
files.  An entire cruise's data is contained in one file (e.g., 
hot1.gof contains the data from HOT-1).  Note that these files contain 
all of the chemistry data. The details of the analytical methods used to
determine all of the parameters listed here can be found in the Hawaii Ocean
Time-series Program Data Report(s).

    It should also be noted that both DOC and pH analytical protocols
have changed causing offsets in the the temporal data sets.  The DOC
protocol changed from the persulfate oxidation (HOT 1-27) to the
high-temperature platinum catalyzed oxidation (HOT 44- present).  The
pH was intially analyzed by the electrode method and calibrated against
NBS scale (HOT 23-32), during 1992 the pH was analyzed by the
spectrophotometric method and the pH calculated on the "total scale"
and converted to the "seawater scale" (HOT 36-present).

    For convenience we have also presented some physical data (i.e. CTD
pressure, temperature, salinity, etc ...) in the hot*.gof files.
A complete description of the physical data for each bottle trip
presented in this file can also be found in the appropriate hot*.sea files. 
Please refer to the Readme.water.woce file for the format description of 
those files.

    The files are self-explanatory; one column is written for each measured
parameter.  Missing data are filled with -9. A five-line heading labels each
column.  Variables having asterisks in their heading have a quality flag
associated with them. These quality flags are concatenated as a quality word
which is listed as the last ten variables in each row (six or seven flags 
per variable).  The values each digit can assume and their meanings follows:

Quality Indicators:
	Flag  Meaning
	 1    not quality controled
	 2    good data
	 3    suspect (i.e.  questionable) data
	 4    bad data
	 5    missing data
	 9    variable not measured during this cast
