Green Iron and KTH are running new tests on manganese nodules. Grinding and briquetting now triples nodule material density.

KTH researchers are testing at what pH seabed nodules dissolve. The nodules' pH is 7.45 versus a bay range of 7.5 to 8.

Robert Venema and the author visited Oceanology International. The next fair is not until 2026.

The company completed a hydrographic survey of the Bothnian Bay. The final report shows 520 hours of seabed footage.

Marine biologist Jonas Gustafsson proposes clearing Baltic dead zones. The model could remove 20,000 tonnes of sediment daily.

Scandinavian Ocean Minerals says seabed nodules yield silicon. It says silicon could cut Sweden's import reliance on China.

A Baltic Sea nodule miner tested its suction-nozzle prototype. It exposed and sorted nodules from sediment on 6 December in a 1:10 scale trial.

Firm surveys seabed after receiving signed exploration permit. Survey covered 15 to 20 percent of permit area, full report due mid-February.

Scandinavian Ocean Minerals says nodule harvesting aids amphipods. Removing hard nodules softens the seabed, letting the amphipod dig down and hide.

A Baltic Sea seabed mining venture has launched its company blog. It has run the project full time for almost four years.
