Thames Manta Project

 Sampling for microplastics on the Thames and Medway.

Despite a number of pieces of work on the Thames and microplastics, there has been no strategic or temporal study of microbeads on the Thames or Medway Estuaries. However with the ban coming in 2018 presents a key point to start to monitor the improvement such interventions make on the environment.

Samples with microbeads

Specific sites will be given to confirmed attendees, timings are for planning purposes. Weather may cause surveying to be cancelled.

Samples and dates

Samples and analyse of the 2018 samples is currently underway.  Dates are below for the first part of the year, sign up now to join us.  Training will be held on one of the Medway dates each month,  the morning of the 4th May and 2nd June.  Most Medway sampling is from midday, except the 1st June which starts at 1100. From Richmond please prepare for an early morning around 0700, London and Gravesend around 0800-0900.
