Falmouth Group 9 2015 Introduction

A time series survey was conducted on the Fal estuary, at the King Harry Pontoon, on the afternoon of the 26th June 2015. Simultaneous physical and chemical measurements were obtained every half an hour between the hours of 12:00 and 15:00 UTC. The aim was to acquire data over a tidal cycle, resulting in 7 tests. Current speed measurements were done with a current meter and light and dissolved oxygen were measured using an YSI probe in order to relate light and turbidity with the chlorophyll distribution. Water samples were taken with a plastic bottle and then filtered for later chlorophyll concentration determination in the lab.
