"BioSwimmer" Tested for Port Inspections
BioSwimmer has the ability to twist and turn in limited space within the water, which sets it apart from most other remotely operated vehicles.
Sea-Source Heat Pump Warms Buildings
The sea-source heating system comprises coils of pipes fixed to 12 stainless steel platforms known as "pond mats" that are sunk beneath a nearby pier and draw heat from the surrounding water.
Shipping May Have Genetic Consequences for Marine Species
Researchers found a mosaic of genetic patterns that could not be explained by the influence of natural or anthropogenic means alone.
Common Drugs Could Damage Aquatic Environments
Although studies of pharmaceuticals in surface waters have been carried out for several decades, there remains little systematic understanding of their transport, fate and impact.
Chemical Record of Fish Could Help Fight Food Fraud
Chemical tests were able to accurately link scallops and herring to their true locations and could be used to test if the chemical composition of an animal matches a claimed area of origin.
A Nontoxic Alternative to Ship Antifouling Paint?
Current antifouling coatings function by releasing biocidal copper, essentially killing everything in the waters around a ship.
Mediterranean's First LNG Passenger Ferry
Compared to standard marine diesel fuel, the LNG solution will reduce CO2 emissions by 25%, nitrogen oxide emissions by 85% and sulfur and particulate matter almost entirely.
Evidence of Deep-Sea Animals Ingesting Microplastics
Among the plastics found inside the deep-sea animals were polyester, nylon and acrylic.
Beaver-Like Wetsuits in the Works
MIT engineers have fabricated fur-like, rubbery pelts and used them to identify the mechanism by which air is trapped between individual hairs when the pelts are plunged into liquid.
Hydrogen-Powered Ferry a Feasibility
To study the issue, researchers drew up conceptual specifications: a 150-passenger commuter ferry traveling four 50-mile round-trip routes each day at a top speed of 35 knots 60% of the time.
UV Provides On-Demand Marine Water Sampling
The ability to collect samples on demand enables better targeting of areas of scientific interest, potentially allowing for more efficient collection of specific samples.
Software Aims to Optimize Ship Operations
SEA-CORES has been developed in response to the increasing complexities of modern warships and the amount of data their systems produce.
Oxybenzone Damages Reefs
Researchers have found oxybenzone concentrations in some Hawaiian waters at more than 30 times the level considered safe for corals.
Nutrient Pollution Is Changing Sounds in the Sea
The demise of biological sounds is likely to have negative impacts on the replenishment of fish populations.
Propulsion Unit to Boost Ships’ Fuel Efficiency
The linear flow Azipod XL uses a nozzle with stator plates that directs the water flow from the propeller to reduce turbulence and energy loss and improve thrust.
Alternative Nuclear Detection Material
Researchers have developed hexagonal boron nitride semiconductors to detect the neutron signals that help identify the presence of nuclear materials.
Software Helps Designers Dampen Ship Vibration
The software guides engineers in developing and simulating elements of ship structures that incorporate actuators and sensors for self-monitoring and control of vibrations.
Saltier Intertidal Beaches Could Endanger Coastal Sea Life
Sediments from some sections of the beach have salt concentrations four times as high as the ocean water that washes over them.
Biodiesel a Fuel Option for Army Workboats
Tests showed both CO and PM2.5 emissions for B100 were significantly less than they were for ULSD or Solazyme.
Crude Oil Causes Deformities in Haddock
Haddock eggshells likely contain a protein that makes them especially “sticky” to oil and its compounds during a 10- to 12-day period of their early development.
