The persistent eutrophication (being too rich in nutrients) of the Baltic Sea prompted the IMO’s Baltic Member States to tackle shipping’s < 0.1% contribution by designating the Baltic Sea as the first Special Area under Annex IV of IMO’s MARPOL Convention [1]. Passenger ships must give sewage to wastewater treatment works (WWTWs) ashore via the port reception facilities (PRFs) or operate a nutrient removal sewage treatment plant (STP) on board prior to discharge. It has been perceived as a positive move. But how special is the Special Area?Rules at sea vs.

Highlighted in Marine Technology Reporter's MTR100 is the work and technology ongoing in the halls of academia. The most recent report released by the UN Intergovernmental Panel on Climate Change emphasized our warming planet, an expected announcement for many in the scientific community. Faced with the confirmation that human activities have caused an increase in global temperatures, research has turned to seeking answers in the planet’s natural systems. How does each part of the global carbon cycle work and how may it be impacted by the changing climate?

New research has revealed the highest levels of microplastic yet recorded on the seafloor, with up to 1.9 million pieces in an area of just one square metre.Published this week in the journal Science, this study shows how deep-sea currents act as conveyor belts, transporting tiny plastic fragments and fibers across the seafloor. These currents can concentrate microplastics within huge sediment accumulations, which the authors of the research term ‘microplastic hotspots’. These…
