New research to help ships locate blue whales to avoid collisions

A new model seeks to enable stakeholders to identify where endangered blue whales are most likely to be, so that ships can avoid hitting them. The research was published after relating the movements of more than 100 tagged blue whales to daily oceanographic conditions.

Cruise ship to be equipped with sustainable waste disposal solution

Wärtsilä informed that it will supply and install an Auto Gasification solution for the ‘Regal Princess’, a Princess Cruises vessel. This technology aims to enable the safe disposal of waste from the ship through a self-fueling thermal decomposition unit.

New technology to listen for whale traffic aiming to prevent ship strikes

Scientists from the Benioff Ocean Initiative and Woods Hole Oceanographic Institution have created a a hydrophone (underwater microphone), in order to listen for whale traffic in the Santa Barbara Channel. With this technology, they aspire to prevent collisions between whales and boats.

Issues arising from ocean warming

With the ocean absorbing vast quantities of heat, increased concentrations of GHG are reported in the atmosphere, mainly from fossil fuel consumption. In fact, the Fifth Assessment Report published by the Intergovernmental Panel on Climate Change (IPCC) in 2013 indicated that the ocean had absorbed over 93% of the excess heat from greenhouse gas emissions since the 1970s. This is leading ocean temperatures to increase.

AIDA Cruises eyes fleet electrification in a world’s first

German cruise line AIDA Cruises, part of Carnival Corporation, signed an agreement with marine battery supplier Corvus Energy, regarding the installation of lithium-ion battery storage systems onboard the AIDA Cruises fleet, starting from 2020.

Ferry in Alaska monitors ocean acidification

The last two years MV Columbia records the ocean’s vitals every three minutes, along a 1,600-kilometer route through the Inside Passage. This includes the coastal region from Puget Sound to the Alaska Panhandle. The ship measures the sea’s temperature, salinity, dissolved oxygen content, and carbon dioxide concentration, aiming to monitor ocean acidification.

Guidelines for use of Electronic Record Books under MARPOL

IMO’s MEPC 74 in May adopted amendments to MARPOL Annexes I, II, V, VI and the NOx Technical Code, regarding the use of electronic record books, approved as alternative of hard copy record books under the MARPOL Convention. The Committee also adopted guidelines to support the use of electronic record books.

Global warming could change waves at half of world’s coast

A new research discovered that a warming planet could change ocean waves in more than 50% of the world’s coastlines. If this happens, it could lead to significant impacts to coastal flooding and erosion. The pattern that is discovered from this research is that changes in wave heights are expected in some areas, with increases in the Southern Ocean and the tropical eastern Pacific, but reductions in the North Atlantic Ocean and portions of the northern Pacific Ocean. 

Researchers catch invasive species in UK with DNA tests

A team of scientists from the University of Southampton, Bangor University and the National Oceanography Centre have found out that several artificially introduced species in the coastal waters of southern England, using a genetic technique that could detect early non-native species if adopted more widely.
