Affordable Multiparameter Water-Quality Probes in 2026: What They Actually Cost
Last updated: 14 July 2026 Most multiparameter water-quality sondes don't list a price. YSI, In-Situ and Xylem all route buyers to a quote request. That makes it hard to answer a simple question: how much does it actually cost to monitor turbidity, temperature, light and current at a marine farm or restoration site? A lot of PEBL's work is with species whose value depends on how well they grow in the water: seaweed, shellfish, seagrass. Growth in all three groups comes down to the same small...
Reflecting on Coastal Futures 2026
Back in January, I attended the Coastal Futures conference in London, one of the UK’s key gatherings for anyone working in marine conservation, coastal management, and ocean policy. It’s always a packed programme, but this year a few themes stood out that feel especially relevant to the work we’re doing at PEBL. The Weather Is Changing Everything A thread running through almost every session was the sheer impact of increasing rainfall and storm intensity on coastal conservation. Whether...
Environmental Impacts of Seaweed Farming
Seaweed grows between 1 to 4 meters below the sea surface on ropes. Ropes link buoys to form a seaweed farm structure that is anchored to...
How can we measure biodiversity at aquaculture sites? A Visual Guide
Biodiversity monitoring in marine environments is a complex task. Underwater ecosystems contain a variety of species, each of which is suited to Different monitoring techniques, from microscopic plankton to large marine mammals. Further complicating matters, these species inhabit many unique habitats, each with their own environmental characteristics such as high turbidity in shallow coastal areas, or low light in deeper waters. This post is a visual guide to some of the main...
Biodiversity monitoring at one of the UK's Offshore Seaweed Farms
Field Update from Bideford Bay Our recent field deployment in Bideford Bay marks the first phase of a multi-year study aimed at assessing...
How to choose the right underwater camera for marine monitoring in UK coastal waters
Addressing strong currents, fluctuating water levels, high turbidity, and low winter light conditions The PEBL SubCam2, mounted and ready for deployment at an offshore wind test site. If you’re monitoring marine biodiversity in UK nearshore coastal environments, you already know how challenging these waters can be. Strong currents, shifting tidal ranges, and low light (especially during winter) make capturing reliable underwater footage a real test of both equipment and fieldcraft. As a...
