Trump's on the DSM grind but at least we have a new shark
Hi everyone!
The header speaks for itself. Let’s dive right in.
News
Nova Scotia startup Clean Valley has developed a patented containerized biofilter system that uses microalgae and oysters to mimic ocean nutrient cycles, cleaning aquaculture wastewater well enough to grow oysters directly within the treatment process. They are now deploying the modular, subscription-based technology across six countries including Brunei, Malta, Portugal, Guinea, Mexico, and Canada.
This Inside Climate News investigation reports that Odyssey Marine Exploration is seeking a federal lease to dredge nearly 2,500 square miles of seafloor off the Delmarva Peninsula for titanium, zirconium, and phosphate-bearing heavy mineral sands (in other words, deep sea mining), drawing fierce opposition from commercial fishers, coastal communities, and environmental groups who warn the project would devastate a biodiverse ecosystem worth $1.3 billion and 7,200 jobs to Virginia's seafood economy.
The Ocean Exploration Trust's E/V Nautilus has embarked on two back-to-back NOAA-supported expeditions to the Mariana Islands this summer, combining ROV, seafloor mapping, and WHOI's AUV Sentry to conduct the first systematic surveys of abyssal plain habitats and ancient seamounts east of the Mariana Trench while live-streaming all dives.
A Pulitzer Center-supported Carbon Pulse investigation profiles Captura, a Caltech spinout that has successfully proven it can remove 1,000 tonnes of CO2 per year from seawater at its Hawaii pilot plant, but finds the company emblematic of the broader mCDR industry's existential dilemma. With no viable CO2 storage site, no regulatory mandate to buy carbon removals, and major buyers pulling back, Captura is pivoting to sell its electrodialysis technology into energy storage and industrial markets just to survive long enough for the carbon credit market to materialize.
The Massachusetts Port Authority is converting Boston's historic No Name Restaurant space on the Fish Pier into a "blue tech" R&D incubator where maritime startups can test prototypes directly on Boston Harbor, as part of Massport's broader Blue Edge initiative to position the Port of Boston as a hub for the region's growing blue economy.
Hatch Blue's Blue Revolution Fund has invested $2 million in Irish startup Nernst Electric, which makes a device that generates pure oxygen on-site at fish farms, replacing expensive and unreliable oxygen deliveries.
