The Dorset Coast (and a little bit of Hampshire!) ~ a virtual field trip ~ I took this picture!
Where it is located
Day 2 – Lyme Regis to Ringstead Bay Day 1– The journey to Dorset!
An aerial photo of Lyme Regis Bay, showing ‘The Cobb’ (Harbour) and where the River Lim meets the sea Groynes
Golden Cap Lyme Regis ~ Charmouth ~ Golden Cap
The cliff top at Black Ven Black Ven between Lyme Regis and Charmouth. Upper Greensand lies over Lower Jurassic clays. The largest coastal mudflow in Europe took place here in the winter of 1958/9 The coast is unstable because there are numerous situations where porous strata, principally the Chalk and Upper Greensand, lie over impermeable clays.
How Landslides occur
Chesil Beach Isle of Portland The Fleet West Bay (west) Pebbles are ’sorted!’ Portland (east) The gradient of the beach can get very steep
The Isle of Portland When the island was uplifted, a series of massive fractures developed in the limestone.
Weymouth is a traditional seaside resort. It is protected by the Isle of Portland. Portland Harbour (South of Weymouth) Weymouth
White Nothe Headland from Ringstead Bay
Day 3 – Ringstead Bay to St. Alban’s head Durdle Door ~ Lulworth Cove ~ Stair Hole ~ Warbarrow Bay ~ Tynham ~ Broad Bench ~ Kimmeridge ~ Winspit
Durdle Door ~ A Limestone Arch Eventually the arch will collapse to leave a sea stack
Limestone Headlands Soft sand and clays Chalk Hills stop the cove eroding any further inland Lulworth Cove
Small arch is only gap in the limestone. Marine processes eroding further inland Stair Hole
The formation of Lulworth Cove, Stair Hole and the future
Worbarrow Bay Tyneham from Gadd Cliff (Note the land use) Broad Bench
Kimmeridge Bay – A wave cut platform
Chapmans Pool St. Alban’s Head Waves shape the coastline. Winspit Winspit (behind)
Day 4 – St. Albans Head to Sandbanks
Dancing Ledge (+ tidal pool!) Looking out to see from Anvil Point Durlston Head Peveril Point Swanage Bay Old Harry Sandbanks Studland Anvil Point
Swanage Bay Swanage
Old Harry Rocks – A stack Stack New cave forming Collapsed Undercutting means stack will collapse
Studland – Sand Dune System Fieldwork (transects!) Little Sea 3 Major dune ridges
Development of Studland – Blown Sands Little Sea
View over dune slack with further vegetation succession Younger dunes with Marram Grass Actual fieldwork! Hmmmmmm!
Day 5 – Sandbanks to Barton on Sea and the Isle of White
