attribute	NC_GLOBAL	acquisition_description	String	Water column chlorophyll samples were size-fractionated using a 'fractionation cascade' . Water passed through a sequential arrangement of three filters: 20 um pore-size polycarbonate (47 mm), 5 um pore-size polycarbonate (47 mm) and 0.7 um effective pore-size glass fiber (25 mm). Preliminary tests showed that 47-mm glass fiber filters had a reduced chlorophyll extraction efficiency compared with filters 25 mm in diameter. Filters were immediately placed in 90% acetone, extracted 24 hr (-20degC, darkness), and analyzed for chlorophyll and phaeopigments a on a Turner TD700 (April, May) or Turner 112 (July) fluorometer. Total chlorophyll concentrations were estimated from the sum of the three size fractions.

attribute	NC_GLOBAL	instruments_0_description	String	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.

attribute	NC_GLOBAL	projects_0_description	String	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.
