ADCP data from the Long-Term Observation Program (LTOP) from Mooring site NH10 on the Oregon Shelf from 1997-2004 as part of the U.S. GLOBEC program (NEP project)

<h4>ADCP U.S. GLOBEC Long-Term Observation Program (LTOP) NH10 Mooring</h4>

<p>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 Hydrographic Line. The nearest standard NH line station is NH10 (10 nautical miles off shore), so this mooring is referred to as Mooring NH10.</p>

<p>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. The mooring is serviced in spring and fall: winter deployments generally use a Sontek 250 kHz profiler with 4 m vertical resolution; summer deployments use a Sontek 500 kHz profiler with 2 m resolution. There are a few data gaps.</p>

<p>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.</p>

<p>The data were collected by Mike Kosro, 104 COAS Admin Bldg, COAS, Oregon State University, Corvallis, OR 97331-5503 (<a href=\"mailto:[e-mail]\">[e-mail]</a>; Phone: [phone]).</p>
