Phytoplankton growth rates and microzooplankton grazing from R/V Alpha Helix HX242, HX244, HX247, HX271, HX275 in the Northeast Pacific from 2001-2003 (NCEI Accession 0114241)

This dataset contains optical and physical data collected on R/V Alpha Helix during cruises HX242, HX244, HX247, HX271, and HX275 in the Gulf of Alaska from 2001-04-17 to 2003-08-09. These data include depth, irradiance, salinity calculated from CTD primary sensors, and water temperature. The instruments used to collect these data include Niskin bottle. These data were collected by Dr Suzanne Strom of Western Washington University as part of the "U.S. GLOBEC Northeast Pacific (NEP)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

The following is the text of the dataset description provided by BCO-DMO:

Phytoplankton growth rates and microzoo grazing

Dataset Description:
Phytoplankton Growth Rates in the coastal Gulf of Alaska

Phytoplankton growth rates, the phytoplankton growth rate response to nutrient enrichment, and microzooplankton grazing rates on phytoplankton in three different size classes were measured during three cruises to the coastal Gulf of Alaska in 2001.

Acquisition Description:
[excerpted from Strom, et al. (2006) Microzooplankton grazing in the coastal Gulf of Alaska: Variations in top-down control of phytoplankton. Limnol Oceanogr in press.]

Water drawn from multiple Niskin bottles closed at a single depth was pooled into two 25-liter polycarbonate carboys. Most often, water was collected from the depth corresponding to 50% of surface irradiance (50% Io, 3 to 10 m). Once during April, and once per station during July, water was collected from the depth of the subsurface chlorophyll maximum (SCM, 12 to 25 m). The contents of one carboy were gravity-filtered (0.2 um) to generate particle-free filtered seawater (FSW, the diluent for the dilution series). The contents of the other were gently pre-screened through 200 um Nitex mesh to exclude macrozooplankton (WSW, the whole seawater for the dilution series). Using gentle siphoning and mixing techniques, FSW and WSW were combined in known proportions in 2.35-liter polycarbonate bottles to generate a dilution series consisting of 9, 16, 24, 41, 61, and 100% WSW (each in duplicate). An additional pair of bottles diluted to 4% was added during the May and July cruises, as well as an additional pair of 100% WSW bottles to control for the effects of nutrient enrichment on phytoplankton growth rate. Clean techniques and inert materials (silicone, polycarbonate) were used throughout.
