It is all change at Margate’s Turner Contemporary this week, as the new autumn exhibitions go on show. What’s On found out more.

Turner and Constable - Sketching from Nature

A major showcase of works by the gallery’s namesake, JMW Turner, along with pieces by John Constable and other contemporaries will be unveiled this week.

Bringing together 75 paintings from London’s Tate Collection, the exhibition explores the practice of sketching and painting in the open air, an approach which became increasingly fashionable during the late 18th and early 19th centuries.

These rarely shown works, radical for their time, demonstrate artists’ efforts to reflect direct experience of their environment, rather than a concern for careful composition.

The exhibition is organised around six principal landscape themes, reflecting interests and subjects common to artists of the period – sketching from nature, the city, the picturesque, the Thames, rivers and coasts and rural nature.

These themes are explored in the works of artistic rivals Turner and Constable, as well as George Stubbs, John Sell Cotman, John Crome, William Henry Brooke and Francis Danby, among others.

• It runs from Saturday, October 5 to Sunday, January 5, 2014

Dorothy Cross - Connemara

Contemporary Irish artist Dorothy Cross is famous for bold pieces including Sapiens - two skulls on a tripod - and Shark Heart Submarine, consisting of a model submarine and a shark’s heart in a jar.

Her work may seem a million miles away from that of conventional painters JMW Turner and John Constable, but all three share the same source of inspiration – the natural world.

Dorothy’s latest exhibition at Margate’s Turner Contemporary is predominantly influenced by her home in Connemara, a rural area on Ireland’s west coast.

The most comprehensive UK solo exhibition to date of her work, it will feature sculpture, film and photography that delves into the relationship between living beings and the natural world around them.

Many of her works incorporate items found on the shore, including boats and animal skins.

One newly commissioned video explores a rarely accessible sea cave near Dorothy’s home, while another crawls through Margate’s Shell Grotto.

It will also include photographs of the Connemara coast, drawing connections to Turner Contemporary’s coastal setting in Margate.

• It runs from Saturday, October 5, to Sunday, January 5, 2014
