BRIEF DESCRIPTION OF DATA FILE: Routinely collected water samples at all creeks, analyzed for temp, salinity and nutrient concentrations

KEYWORDS: nitrate, phosphate, ammonium, salinity, temperature, chlorophyll

RESEARCH LOCATION:

Creek

Branch

Transect

Habitat

NE, CL, WE, SW, Rowley River

R, L and Confluence

Only sampled at confluence and 50m up the R and L branches

Channel

 

EXPERIMENTAL DESIGN AND METHODS:  Sites visited every 3-4 weeks at mid ebbing tide (approx. 2.5 hours after peak high tide).  Samples collected from creek channel at three locations at each study creek (confluence and 50m up the right and left branches).  Temperature readings collected at confluence.  Samples transported back to the lab for salinity reading using refractometer and filtration for nutrient subsampling.  Filter collected for dissolved chl a.  Nutrient samples frozen until time of analysis.  All analysis conducted at the MBL according to standard lab procedures (see methods).
