Environmental Groups Call on Norway to Stop Deep-sea Mining Plans

Six environmental organizations, including the World Wildlife Fund and Greenpeace, on Monday, called on Norway to stop plans to open ocean areas for deep-sea mining.The government in January launched a process to open areas on its extended continental shelf for exploring and producing minerals from the ocean floor, with plans to issue the first licenses as early as 2023."Minerals and metals for the green shift should be obtained from consumption reduction and better reuse on land, not from the depths of the sea where brutal mining can do irreparable damage to nature," the environmentalists

The James River is a tributary of the Missouri River. It is roughly 710 miles long and spans over 20,000 square miles of North and South Dakota with more than 70% of the river’s drainage occurring in South Dakota. River conditions during normal years include both still-water and flooding on both the James River and its tributaries. Water easily breaches the low banks, and these floods tend to cover a significant portion of the floodplain. When the river is still, water quality drops and it becomes quite difficult to see more than a few feet underwater.The Beadle County Office of Emergency

of Science and Technology (KAUST), an expedition performed by the Caladan Oceanic crew and Victor Vescovo, renowned explorer, investor, and retired naval officer, reached the deepest point achieved by man in the Red Sea—the Suakin Trough.Using the DSV Limiting Factor submersible from Triton Submarines, manned dives were completed to the Suakin Trough (2,777 m/9,111 ft) and the Kebrit Deep (1,470 m/4,823 ft), making Vescovo the first person to physically reach these points in the Red Sea. Accompanying him on the dive at the Kebrit Deep was Dr. Alan Jamieson from Newcastle University; with him

Mediterranean Marine Life Flourishes During Lockdown

Marine life in the Mediterranean off Italy flourished during the coronavirus lockdown as water quality improved and species moved into spaces vacated by people and ships, the Italian coastguard has found.The strict rules halting business and movement for two months offered an unprecedented opportunity to monitor the impact of human activity on the sea that surrounds Italy.Since April, the coastguard has used water samples, underwater footage filmed by remotely operated vehicles and its own divers, and a census of unusual sightings of marine species close to heavily populated areas to monitor the sea.

SOI: Amidst Pandemic, Seafloor Mapping Zooms Ahead

a first look at deep waters in the Coral Sea, despite the continuing COVID-19 pandemic. As one of the only at-sea science expeditions to continue operations, the team has discovered the deepest living hard corals in Eastern Australian waters, sighted fish in new regions and identified up to 10 new marine species.SOI’s R/V Falkor spent the 46 days in the Coral Sea Marine Park, one of the largest protected areas in the world. Scientists connected remotely to the ship from their homes, collecting high-resolution seafloor maps and video footage of the ocean down to 1,600 meters. Led by chief scientist

New Study Tracks Trash Found at the Ocean's Depths

While deep-ocean exploration is responsible for ground-breaking discoveries, it is also unmasking the true scale of our impacts in the deep ocean. Marine debris is a growing problem, and a new study has shown that even unexplored, remote and protected areas of the central and western Pacific deep ocean are not immune from our touch.Coordinated deepwater exploration from 2015 to 2017 via remotely operated vehicle expeditions conducted onboard NOAA Ship Okeanos Explorer and the Schmidt Ocean Institute’s Research Vessel Falkor enabled new insights into the status of deep-sea marine debris. These

MBARI: Hydrothermal Mapping is Heating up

A recent paper by Monterey Bay Aquarium Research Institute (MBARI) has revealed almost 600 hydrothermal chimneys around the Endeavour Segment of the Juan de Fuca Ridge, about 350 kilometres (220 miles) northwest of Washington State. The vents, located in a valley about 14 kilometres (8.6 miles) long and 1.5 kilometres (0.9 miles) wide, has been studied previously, but never mapped until now because of difficult access.Hydrothermal vents are created by magma beneath the seafloor that heats water within the surrounding bedrock, emerging from the seafloor in the form of underwater seeps and geysers.

Forecasters Expect Busy 2020 Atlantic Hurricane Season

U.S. forecasters expect an above-normal 13-19 named storms during the 2020 Atlantic hurricane season from June 1 through November 30, the National Oceanic and Atmospheric Administration's (NOAA) Climate Prediction Center said on Thursday.NOAA forecasters estimate three to six major hurricanes packing winds of at least 111 miles per hour may form. The last two years have seen an above-average number of named storms with 18 last year and 15 in 2018. An average hurricane season produces 12 named storms, of which six become hurricanes, including three major hurricanes.The combination of several

This makes it ideal for supporting marine operations conducted in rivers, lakes and coastal waters. The system has an operating range of 995 meters and can update the position of each target being tracked up to twice a second.Micro-Ranger 2 calculates the position of underwater targets using a transceiver at the surface to transmit an acoustic

Submarine Vermont Delivered to the US Navy

General Dynamics Electric Boat Friday delivered the nuclear-powered attack submarine Vermont (SSN 792) to the U.S. Navy.Vermont is the 19th submarine of the Virginia Class, and the first of the 10-ship group of Virginia-class submarines known as Block IV.Virginia-class submarines displace 7,835 tons, with a hull length of 377 feet and a diameter of 34 feet. They are capable of speeds in excess of 25 knots and can dive to a depth greater than 800 feet, while carrying Mark 48 advanced capability torpedoes and Tomahawk cruise missiles.
