AIMS:
Over the course of our 12 day study in Falmouth, we aimed to gain insight into the
chemistry, biology and physics of the marine environment in Falmouth. This was achieved
by collecting, analysing and reviewing data collected by the team through various
boat trips offshore, within the estuary and from King Harry’s pontoon. Furthermore,
since data has been collected here annually for 12 years consecutively, we hoped
to utilise the time series data to investigate any temporal changes by comparing
our own data to that of previous years. This is especially important due to the Fal
Estuary’s Special Area of Conservation status. There were five primary survey methods:
an offshore survey on board MTS Terramare examining stratification in the estuary
in relation to the Deep Chlorophyll Maximum and thermocline; an estuarine survey
on R.V. Bill Conway in the Fal estuary to investigate estuarine mixing through the
use of transects; a stationary survey at King Harry’s Pontoon over the course of
3 hours to examine how the properties changed with time and changing tide; transects
and data collected by Winnie the Pooh in the most riverine part of the estuary; and
a habitat survey within the estuary on Xplorer using video recording, Van Veen grabs
and side scan sonar along transects to investigate the seabed habitat.
