Temperature and Salinity U.S. GLOBEC Long-Term Observation Program (LTOP) NH10 Mooring Data

A long-term mooring site on the Oregon shelf (44.6467N -124.3067E) was established in August 1997 and maintained with few gaps through December 2004 with U.S. GLOBEC funding. The mooring is at 81 m water depth, near the historical Newport Hydrographi Line. The nearest standard NH line station is NH10 (10 nautical miles off shore), so this mooring is referred to as Mooring NH10.

Upward looking acoustic Doppler current profilers have been used to measure vertical profiles of water velocity (insert actual sample interval here) at 2 or 4 m vertical intervals depending on instrument (data elsewhere on U.S. GLOBEC data server). The mooring is serviced in spring and fall. Temperature records are available for 11 depths; salinities for 4 depths. There are a few data gaps.

Temperature and salinity are processed using a cosine-Lanczos filter with a 40-hr half-power point. Six-hourly data included here are temperature (deg C) and salinity (PSS: unitless).

The data were collected by Mike Kosro, 104 COAS Admin Bldg, COAS, Oregon State University, Corvallis, OR 97331-5503 ( kosro@coas.oregonstate.edu; Phone: 541-737-3079).

Currents are processed using a cosine-Lanczos filter with a 40-hr half-power point. Six-hourly data included here are Eastward (u) and Northward (v) velocities in cm/s interpolated to 2 m depth bins.

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).
