up for Seasearch Courses - going fast!
is the time to sign up for the remaining Seasearch courses for the
year. We always try to run as many courses as possible in the spring
and there have been 22 already this year. We are now moving onto
the main surveying season so if you do want to join us sign up for
one of the remaining courses. They are:
June, North Yorkshire (to be confirmed but likely to replace the
originally planned Surveyor Course)
July - Selsey (Sussex) and Weymouth (Dorset) both with course
on the Saturday followed by Sunday diving
July - Dublin
July - Sheringham (Norfolk)
June - Poole (Dorset) and Killary Harbour (Galway, Ireland)
June - Ascidians - Marloes (Pembrokeshire)
July - Hydroids and their Predators - Falmouth (Cornwall)
July - Marine Life ID - Swanage (Dorset)
August - Marine Ecology - Swanage (Dorset)
Spetember - Photogtaphing Marine Animals - Swanage (Dorset)

sighting of rare southerly nudibranch
rather distinctive nudibranch with black rhinophores and gills was
recordedrecently at Hilsea Point, Devon and has been identified
by Bernard Picton as Cadlina pellucida. Bernard says "Currently
known from Portugal and NW Spain, but certainly never on our side
of the English Channel. Is it another one moving North?"
One to look out for then - this one was spotted by Allen Murray
and the photo is from Alec Jacobs
The Holothuria poo gives it a nice bit of scale!
it is the second sighting as Seasearchers David Kipling and Sarah
Bowen also found it in Cornwall in 2012.
Surveys underway at last
May 18th/19th weekend was a good one for survey diving for some.
In Devon Seasearch visited 4 sites east of Plymouth, Blackstone
Point, Stoke Point, East Rutts and Prawle Point, with 10m visibility
at three of them and a thick mid-water layer of plankton at the
fourth. In North Wales Seasearch visited Bardsey Island and there
were also dives planned in Poole Bay and West Pembrokeshire.
sea temperature in Devon has finally reached double figures after
being a couple of degrees below normal thoughout March, April and
the beginning of May.
is the best time of year to observe many of the hydroids and the
nudibranchs feeding on them. Below are dense oaten pipe hydroids
from East Rutts Devon, and a pair of, anemone eating, Aeoilid nudibranchs

are still places available on many of the Seasearch Surveys dives
over the summer. See the full list on the Diving
page of the site. There are often spaces at the last minute so even
if you find the event is currnetly full do ask to be put on the
have now received over 200 records from surveys so far in 2012.
Most of them come from England (57%), follwed by Wales (14%), Ireland
(10%) and the Channel Islands (9%).
data for 2012 now online
Seasearch dataset on the National Biodiversity Network has now been
updated to include all of the 2012 data collected by our volunteer
recorders. The dataset now includes 404,000 records from 9.089 sites
and covering 2,752 species.
dataset includes all of the data collected by Seasearch, and some
earlier UCS/MCS surveys, going right back to 1977. The graph shows
how the number of records collected by Seasearch has expanded over
the years and 2012 was our second best year ever, despite the challenging
the records for England, Wales, Scotland, Northern Ireland, the
Republic of Ireland and the Isle of Man can be viewed online. At
present the NBN is unable to display data from the Channel Islands
but we hope that will also be available soon.

we have all of the data for 2012 logged and entered into the Marine
Recorder database we know that the final tally was 1,861 forms of
all types (Observation, Survey and Sea Fan). Whilst this is 13%
down on the highest figure ever, in 2010. The good news is that
the number of Survey Forms is the highest ever and the proportion
of Survey Forms is a record 43%. Survey Forms typically provide
us with three times as much data as Observation Forms and we have
prioritised getting our volunteer divers to make the transition
from one to the other in the last couple of years. This has been
successful as the figures show.
the pie chart shows, almost half of the data comes from England,
though Wales, Northern Ireland and the Isle of Man have achieved
well above their size. Northern Ireland has recorded twice as many
forms in 2012 as in any of the last 5 years.
success story in England is the North Sea coast with a record number
of forms from the North East. In fact records from the North East
and East make up 37% of the total for England. It's an enormous
achievement for Seasearch divers along our North Sea coasts, always
considered to be difficult to dive and very under-recorded.
also saw many more tageted surveys, especially in the recommended
127 new Marine Conservation Zones in England, and reports on these
are listed below. However the government has only brought forward
31 of the 127 sites and none of those which propose highly protected
'no take' status.

fan anemones can damage sea fans
new Seasearch report has just been published on a six-year photographic
monitoring project carried out on the wreck of the Rosehill in Whitsand
Bay, Cornwall by Sally Sharrock of Devon Seasearch. The sea fan
anemone Amphianthus dohrnii is a BAP species because of
its rarity and lives almost exclusively on our two species of sea
fan. The report compares pictures of the same sea fan between June
2006 and May 2012 showing how the anemones have affected the fan
and caused necrosis leading to fouling and finally breaking off
of sections of the colony. The report also looks at the Seasearch
records of Amphianthus in South Devon and East Cornwall
and concludes that they are ephemeral at most sites, though the
cause of the fluctuating population is unknown.

2012 Seasearch reports published
are now 23 Seasearch reports for 2012 published all of which can
be downloaded from the Achievements
page. The latest two are from Kent and Wales:
Summary 2012 is a summary of the Seasearch
activity in Kent in 2012.
Summary 2012 is
a summary of all of the Seasearch activity in Wales in 2012
are 2012 summaries for Northern Ireland, North-East England, Devon
and Dorset already on the site and there are more to follow.
Training and Qualifications
programme of Observer, Surveyor and Specialist Courses for 2013
is now well underway. Go to the Training
page so see the list. There are more in the planning stage which
will be added as soon as dates are confirmed.
April and May two volunteers completed their Observer Qualification.
They are Kerry Netherway (E) and Andrew Woods (E).
Surveyors in April and May are Cat Wilding (E), Tony O'Callaghan
(I), Matthias Biber (W) and Caroline Perry (IOM).
