The research vessel 'Plymouth Quest' returning to her berth in Sutton Harbour yesterday.
She is operated by the Plymouth Marine Laboratory,
a globally recognised, independent academic institution, which specialises
in delivering pioneering research into the many challenges facing the planet's marine environment.
In a matter of minutes she is through the lock gates and moored behind 'Sepia',
one of the institution's smaller research vessels.
Although it looks like a summer day the temperature barely rose above 0 degrees C all day.
