Chesil Beach Cove, 07/26/2012

Observer Name: Nina Hukkanen (w/Izzy)
Observation Start Time: 16:00
Observation End Time: 17:10
Weather Conditions: Sunny and calm
Depth of Observations (indicate meters or feet): 7-8m (parallel to shore)

Water Visibility (high, medium, low): Medium avg. 4 m
Water Turbidity (high, medium, low): Medium (Particles and plankton)

Water Current Direction: S-N
Water Current Speed (high, medium, low): Low with slight undertow
Water Temperature (indicate C or F): 15C
Notable Flora: Seaweed, kelp (& kelp forest)

Notable Fauna: Sea hare populations, pollock, wrasse
Other Observer Comments: Check out the Chesil  Factsheet or Chesil Photo Album


Izzy and I decided to continue to sketch underwater way-points for the two anchor/monitoring sites (Preveza and old pipeline) following an underwater trail towards the South and keeping at a maximum eight metres depth parallel to shore.  Of the marks in the sketch below the boulders seems to have the densest population of sea hare especially where there is strong undertow. The pipeline (to the right of the sketch) is where a genuine kelp forest starts, leading out the length of the pipe (where we are unable to spot any Monkfish although there have been previous reports). There are a lot of spent fishing line at certain point of the pipe which will need a separate dive and some effort to remove. Pollock and the occasional wrasse (did we say sea hare?!) are the main population in this stretch but careful study of the pebbles will reveal baby pipefish. It is probably too shallow for the smaller cuttlefish though. As soon as the kelp forest starts (boulder to the left of the pipe  in the sketch) the wrasse are larger and in many colours from the rainbow to yellow. A more extensive report and video will follow -- as well as a trip to recover and remove the line from the pipe.

Chesil Beach Cove, 07/26/2012

Observer Name: Izzy Imset (w/ Andy)
Observation Start Time: 13:00
Observation End Time: 14:10
Weather Conditions: Calm and Sunny
Depth of Observations (indicate meters or feet): 10-12m
Water Visibility (high, medium, low): Medium 5-6m
Water Turbidity (high, medium, low): Medium (Plankton)
Water Current Direction: S to N

Water Current Speed (high, medium, low): Low
Water Temperature (indicate C or F): 15C
Notable Flora: See Cheryl's Log
Notable Fauna: Pollock, wrasse, sea hare populations, 3 lobsters, plenty of sand eels, several (one very large) 'edible' crabs, notably not many velvet swimmers or spider crabs around. In fact, not a single large spider crab - worth looking out for numbers and sightings. On the shore line under the 'green weed' there are smaller crab and baby pipefish hiding (distinguished mainly by their tails that protrude out of the pebbles). There are also a number of baby (curious) cuttlefish about.
Other Observer Comments: Gery and Angel (w/ Nina) spotted a number of cuttlefish on their dives and have taken some very good photographs and video of them.  More of our photos are here.

Chesil Beach Cove, 07/25/2012

Observer Name: Izzy Imset (w/ Nina)
Observation Start Time: 11:40
Observation End Time: 12:45
Weather Conditions: Calm and sunny
Depth of Observations (indicate meters or feet): 10-15m
Water Visibility (high, medium, low): Medium 5m
Water Turbidity (high, medium, low): Medium (Plankton)
Water Current Direction: S to N
Water Current Speed (high, medium, low): Low (+undertow)
Water Temperature (indicate C or F): 15C
Notable Flora:
Notable Fauna: A number of baby cuttlefish and sea hares close to the shore, the latter appear to be mainly in mating chains. Large 'edible' crabs and one lobster sighting under the rocks between 10-12 metres. Occasional Pollock and plenty of sand eels over the sand beds. One dogfish (on video). This time no Plaice sighting. Of interest is the observable decline in the nudibranch population (colonies replaced by individuals 'hanging about') but a major increase in the population of predominantly brown-red sea hare. It does appear sea hare especially like where the undertow is strongest, clinging on to branches and weeds as they are 'tossed about'.
Other Observer Comments: Liter underwater in the form of spent fishing lines and lost hooks that have gathered together and much more on the shore line where the tide cuts in. Most of the liter on the beach was gathered in spots -- easier to collect if pickup could be organised.

Water Temperature (indicate C or F): 15C
Notable Flora: Kelp, Sugar Kelp, Aplidium punctum, Boring Sponge, Morchellium Argus, Hydrallmania Falcata, Pot Weed, Sea Mat
Notable Fauna: Sea Hare (many, mostly mating), candy stripe flatworm, compass jelly fish, very large edible crab, school of juvenile bib, ballan wrasse, ling, large plaice, Ling, velvet swimming crab, spider crab, sand eels, Onchidoris Luteocincta (Fried Egg Sea Slug), Mermaids Purse -- Other divers saw 'baby' cuttlefish too.
Other Observer Comments: Dived at low tide in a group (Nina Hukkanen & Izzy Imset). Dropped in on a direct line from the ramp and on a bearing of 220 hit wreckage (the Preveza) at 5m. Large population of Sea Hare would appear to be their mating season. Click for a photo album of the Project Baseline Chesil Beach Dives - July 2012
