Good periods of settled weather have allowed our surveyors to take advantage of the large autumn tides and complete a range of survey programmes.
September has been a busy month for our surveyors. Good periods of settled weather have allowed them to take advantage of the large autumn tides and complete a range of existing and new survey programmes.
One of the field surveys involved a comprehensive intertidal habitat mapping exercise in Wales. To accurately map the extent of the intertidal habitats, we used Real Time Kinematic (RTK) Global Positioning System (GPS) as well as fixed point and elevation imagery. Our Survey Team also used quadrat-based sampling to characterise rocky epifaunal communities and collected sediment samples to record infaunal biota. The survey recorded a range of notable habitats in the area including honeycomb worm (Sabellaria alveolata reef), seagrass (Zostera spp beds) and diverse boulder communities.
Other ecological surveys this month have included ongoing intertidal benthic and saltmarsh monitoring at the Welwick and Chowder Ness managed realignment sites on the Humber Estuary. We have been collecting data at these sites for over ten years giving us a valuable dataset to understand how these sites have developed over time.
As well as completing ecological surveys, our Survey Team has been in Scotland undertaking topographic beach monitoring (using RTK GPS). The data collected is used to create beach profiles of a number of specified locations within Aberdeen Bay to help assess any changes in the height and shape of the beach.
Our survey work at the RSBP RSPB Wallasea Island Wild Coast Project (Essex) has also continued this month, as part of an annual programme of post-consent monitoring. This year the main work has involved topographic measurements (again using RTK GPS) to describe the physical development of the newly restored intertidal habitats. It also included further measurements of the tide level and water quality conditions (suspended sediment and dissolved oxygen) within the site and bathymetric surveys of the adjacent Crouch and Rouch estuaries to verify that the site is functioning as it was designed.
