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