Marine Geography: resources to bridge
secondary and higher geography
Dr Rupert Perkins, Senior Lecturer in Marine Biosciences
Degree Scheme Director and Admissions Officer
What is Marine Geography?
A blend of human and physical geography in the coastal
and offshore marine systems.
Covering marine biology, fisheries, conservation, offshore
energy, renewable energy, ports and shipping,
geomorphology, geology, coastal processes, hydrographic
survey, mapping and charts, meteorology, climate and
climate change, sustainability, food supply and logistics,
water supply, environmental pollution, hazards and risk,
coastal management, marine governance, environmental
law......

Coastal Erosion – Diatoms play at King Canute
Coastal erosion costs millions and with IPCC predictions
for sea level rise, things can only get worse
Problem – coastal defence can cost more than the value of
the land being saved as has a finite life span
Work with nature –
Managed
Realignment
So how do Diatoms help?
Migration – Extracellular Polymers – Biofilm Biostabilisation

Abbotts Hall Farm,
Blackwater estuary, Essex –
Environment Agency – “it
has been a huge success,
particularly in mitigating the
flood risk further up the river
in populated areas.”
"It's a really great site to take
the pressure out of the tide.
On big surge tides it is not
going up and overtopping
other defences," she said.
