2012 UCSB Washburn/LTER/PISCO Lab

My camera’s sensor frame is broken. That’s Ed in the PISCO lab.  That’s the computer used to program TidBits in HOBOware and BoxCarPro 4.0.

ADCP Acoustic Doppler Current Profiler (ocean current profiler)

TidBits (temperature loggers)  These are intended to monitor food temperatures for transport, but oceanographers use them to monitor ocean temperatures.  They can be mounted on a line at various lengths to measure temperatures at desired depths.

2012 UCSB Washburn Lab, ARC Program

This is a Wave Pressure Data Logger, which is made in the UCSB Washburn lab.

This instrument detects changes in wave pressures from changing wave heights.  It measures four times a second in absolute water pressure.  This high sampling rat is needed to capture such intricate pressure changes in surface waves.  It is powered by four D-cell Batteries, which and run up to three months.  Data is stored on to a 2GB SD card.  

The test button verifies the battery voltage, configuration files, recording pressure, and connections.  The start and stop botton record the start and stop times of sampling.

The instrument is protected with clear PVC tubing, and rubber o-rings prevent water leakage.

Stearns Wharf - Sensor repair and water sampling

Stearns Wharf has an instrument pack behind the Crab Shack.  It is mounted on a piling 10 ft below water surface.  Real-time data of conductivity, temperature, depth, pressure, pH, DO, and chlorophyll is recorded and can be seen at http://sbc.lternet.edu/data/stearns_wharf/index.php 

SBC LTER data at Stearns Wharf was displaying a high concentration of chlorophyll from the SeaFET, which displayed a plateaued of data.  I assisted the dive retrieval of the SeaFET and instrument pack.  When it came time to return the instruments, one of the divers, David Salazar noticed one of the CTD pins was broken.  This led to taking the pack back to the lab… that’s why when you click on the link there is no data right now.
