CTD Rosette Bottle Data from New Horizon cruise July 28 - August 12, 2000 (NH0007).
(1) Actual Rosette Bottle Number (1-12) is obtained by dividing shown Bottle Position by 2 (e.g., 12 shown = 6).
(2) Chlorophyll readings done by Leah Feinberg.
(3) Chl_QCF is a quality control flag for the extracted chlorophyll data. Flagged 1 for samples that may have been rinsed with unfiltered rinse water.

(1) Nutrient samples were collected from most bottles; all nutrient data developed from samples frozen during the cruise and analyzed ashore; data developed by Burke Hales (OSU).
(2) Bottle Salts were run by SIO techs on Guildline Autosalinometer.
(3) sal (sal00) - salinity calculated from primary sensors (C0,T0) differ from bottle salts by less than 0.003 psu.
(4) sal2 (sal11) - salinity calc. from secondary sensors (C1,T1) differ from bottle salts by ca. 0.0088 psu.
Operation Detection Limits for Nutrient Concentrations (Units are micromoles per liter):
PO4 Range: 0.003-0.004; Mean = 0.004
NO3+NO2 Range: 0.04-0.08; Mean = 0.06
Si(OH)4 Range: 0.13-0.24; Mean = 0.16
NO2 Range: 0.003-0.004; Mean= 0.003
BCO-DMO replaced single digit day and month values with 2-digit values (ie. replaced '7' with '07').
08/17/12: BCO-DMO added lat and lon from the NH0007 event log station locations.

Niskin bottle cast used to collect water samples for pigment, nutrient, plankton, etc. analysis
|Generic Instrument Description|| |
A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Program in a Nutshell
Goal: To understand the effects of climate variability and climate change on the distribution, abundance and production of marine animals (including commercially important living marine resources) in the eastern North Pacific. To embody this understanding in diagnostic and prognostic ecosystem models, capable of capturing the ecosystem response to major climatic fluctuations.
Approach: To study the effects of past and present climate variability on the population ecology and population dynamics of marine biota and living marine resources, and to use this information as a proxy for how the ecosystems of the eastern North Pacific may respond to future global climate change. The strong temporal variability in the physical and biological signals of the NEP will be used to examine the biophysical mechanisms through which zooplankton and salmon populations respond to physical forcing and biological interactions in the coastal regions of the two gyres. Annual and interannual variability will be studied directly through long-term observations and detailed process studies; variability at longer time scales will be examined through retrospective analysis of directly measured and proxy data. Coupled biophysical models of the ecosystems of these regions will be developed and tested using the process studies and data collected from the long-term observation programs, then further tested and improved by hindcasting selected retrospective data series.
U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.
The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).
