Bodega Head Intertidal Shore Station

 

Bodega Head Intertidal Shore Station

Station History

The Bodega Head intertidal shore station is rigidly mounted to the rocks in the intertidal zone and is maintained by Sonoma State University. Data from this station is not transmitted in real-time, it is manually downloaded at the end of each deployment. The station is comprised of sensors that monitor water temperature and chlorophyll.

Sensor Information


Temperature

Onset TidbiT v2 Water Temperature Data Logger - UTBI-001 . Specifications reported by Onset for this product are as follows: temperature sensor accuracy: ± 0.2°C (from 0° to 50°C); resolution: 0.02°C (at 25°C); response time: 5 minutes in water to 90% and drift: 0.1°C per year; time accuracy: ± 1 minute per month (0° to 50°C). In some cases when the primary data logger at a site failed, temperature data from a HOBO Pendant® Temperature/Light Data Logger 64K - UA-002-64 were substituted. Specifications reported by Onset for this product are as follows: temperature sensor accuracy: ± 0.53°C (from 0° to 50°C); resolution: 0.14°C (at 25°C); response time: 5 minutes in water to 90% and drift:< 0.1°C per year; time accuracy: ± 1 minute per month (at 25°C).


Chlorophyll

WET Labs ECO FL fluormeter with the following manufacturer specifications: excitation/emission wavelengths: 470/695 nm; sensitivity: 0.02 µg/l; and range: 0-125 µg/I. Fluorometers were installed in the mid-intertidal zone (~ 0– 0.3 m above MLLW) Bodega Head (38.318739, -123.074186) in California, USA. The instrument is encased in a custom-made, secondary PVC case and then affixed to the rock using 3 stainless steel mesh straps and stainless steel lag screws screwed into high tension plastic anchors set into pre-drilled holes. The instrument face is oriented downward and towards the water. Observations are logged every 15 minutes. The sensor face is cleaned every 2 weeks when possible but no less than every 4 weeks (depending on sea state). Instruments are typically deployed between January and March and then retrieved between September and November of each year. They are sent back to the manufacturer for servicing and re-characterization annually.
