Fruits of the Thames

As part of Wrecked on the Intertidal Zone, a series of investigations into the Thames Estuary YoHa and Art Catalyst are holding three FREE workshops in Leigh-on-Sea to digest and map the Fruits of the Thames.

Details of each workshop, clothing and equipment required can be found below.

These workshops lead on from the workshop Eating and Smoking the Flowers of the Thames held in July 2014 at Leigh-on-Sea’s Maritime Festival.

Catastrophe can afford a certain optimism. Many would say the worst has already happened to Two Tree Island, Leigh-on-Sea, situated on the north bank of the Thames Estuary. From 1936 to the mid-1980s the site was used as landfill and a sewage works, leaking PCBs, DDT and other nasties into the salt marsh. Southend-on-Sea and Castle Point local authorities have little data about what lurks beneath the uneven rubble, plastic bags of dog poop, half-empty 1950s Brasso tins, chip wrappers and the ruins of long-forgotten Southend-on-Sea property booms. In 2004, the Island’s chemical cocktail leached into the genomes of surrounding shellfish percolating to public attention in Parliamentary questions.

In recent years Essex Wildlife Trust and a host of local volunteers have transformed the Island into a haven, allowing wild Essex to perch on top of its abandoned urban filth.  Today beautiful — and sometimes exotic — wild apples are tempting to eat, blackberries flourish and cry out to be jammed; fennel, shellfish and sea aster spring from once-contaminated soil. Two Tree Island is not too different from anywhere else in the UK, where the worst of poisonous substances and their potential hide beneath the surface.

Workshop Details

Digital Mapping, Introduction to Citizen Science with Andy Freeman

Date and Time: (weather permitting) Sunday14 September 10am to 4pm

Meeting point: The Fisherman’s Chapel, New Road Methodist Church, New Road, Leigh-on-Sea, SS9 2EA (5 minutes walk from Leigh-on-Sea railway station)

With GPS enabled camera phones and free online tools its now easier than ever to make useful, fun and beautiful maps that can show anything from your holiday snaps to the distribution of edible plants in polluted soil.

Andy Freeman will introduce a range of techniques for making and sharing maps using simple digital methods. The workshop includes a walking tour of Two Tree Island where participants will learn how to collect geo-tagged images and data using either their mobile phone or equipment supplied on the day. Data we hope to collect and map on the day includes:

- aerial photography using a drone and/or kite (weather dependent)

- geo-tagged photos

- air quality

- sampling water for pollutants

- ambient sounds

- ambient electromagnetism

- background radiation

- the blueness of the sky (using a cyanometer)

Participants will get a chance to add their data, images and observations to online open maps produced on the day or produce their own map. The workshop runs from 10am-4pm and includes light refreshments. Participants are welcome to bring their own laptops, tablets and cameras to build their own maps as wi-fi will be available, but this is not a requirement of participation.

Protective clothing and equipment

To take part in this workshop you will need comfort clothing, walking shoes and rainwear. You can also bring smartphones, laptops, tablets and cameras as wi-fi will be available for the indoor parts, but this is not a requirement for participation in the workshop.
