BRIEF DESCRIPTION OF DATA FILE:

15 minute readings of water column temperature, salinity, oxygen, depth, and turbidity in Plum Island Sound at the Ipswich Bay Yacht Club.

KEYWORDS: temperature, oxygen, conductivity, salinity, turbidity, depth, dissolved, saturation, gas, sound, monitoring

SITE TYPE: Monitoring

RESEARCH LOCATION: MON-SO-IBYC YSI

Mouth of Plum Island Sound, on Ipswich Bay Yacht Club pier, Ipswich, Massachusetts.

Latitude 42o 42’ 32.38”, Longitude 70o 47’ 47.85”

EXPERIMENTAL DESIGN AND METHODS:

Measurements are made using a YSI 6600 water quality sonde and YSI 6200 Data Collection Platform (DCP) with data radio telemetered to the PIE LTER Rowley field station. YSI Sonde sensors consist of 6562 dissolved oxygen probe (rapid pulse – Clark type,polarographic), 6560 conductivity/temperature probe (thermistor), vented level depth sensor (stainless steel strain gauge), 6026 wiping turbidity probe(optical, 90o scatter) and 6025 wiping chlorophyll probe (optical fluorescence).

NOTES AND COMMENTS: Chlorophyll and fluorescence data typically does not calibrate well and data should only be used for relative purposes of looking at highs and lows of phytoplankton blooms not real concentrations.
