Falmouth Group 9 2015 Introduction

On Thursday 2nd July, group 9 set out on the Bill Conway to collect samples from the Fal estuary. Due to tidal conditions, the first station was located at the most northern point of the estuary and four other stations positioned successively towards the mouth of the estuary (near Black Rock). Sampling conditions were satisfactory, however a sustained rain shower was present each station until station 5, at which precipitation stopped and cloud cover reduced.


AIM: to assess any changes in chemical, physical and biological composition along the Fal Estuary using surface measurements and vertical profiles.
