Low Gravity on Ocean Worlds Might Help Sustain Warm Water Circulation
loss," said Andrew Fisher, study lead author and a distinguished professor of earth and planetary sciences (EPS) at UC Santa Cruz. "The entire volume of the ocean is pumped in and out of the seafloor about every half-million years.""Many previous studies of hydrothermal circulation on Europa and Enceladus (moons of Jupiter and Saturn) have considered higher temperature fluids, and cartoons and other drawings often illustrate systems on their seafloors that look like black smokers on Earth," explained Donna Blackman, an EPS researcher at UC Santa Cruz and third author on the new

on Mars, might be able to adapt to an increasingly drying plane,” said Dr. Azua-Bustos, “We hope the information we gathered from the Atacama trench, with help from the Schmidt Ocean Institute, will aid us in searching for biosignatures should we eventually study the oceans of Enceladus and Europa on Saturn and Jupiter, water worlds that may potentially support life.”The science team, including Dr. Guillermo Guzmán, Dr. Nikolaos Schizas, and Professor Alexis Gacitúa, also collected more than 70 specimens, with many species suspected to be new to science. Pending further
Why There May Be Oceans Inside Dwarf Planets Beyond Pluto
1979 paper by astrophysicist Stan Peale. This predicted that Jupiter’s innermost large moon, Io, would be so hot inside that it could be volcanically active.The heat source that makes this possible is a gravitational effect – a repeated tidal tug between Io and the next moon out from Jupiter, Europa. Europa completes exactly one orbit for Io’s two. Io therefore overtakes Europa after every two orbits, receiving a regularly repeated tidal tug from Europa that prevents Io’s orbit from becoming circular.This mans that Io’s distance from Jupiter is continually changing, and therefore
Subsea Vehicles: A Journey to the Under – and Outer – Worlds
JPL than that. There are six ocean worlds in our solar system, explains Shank. These are ice-covered oceans on various moons. “You’re looking at kilometers and kilometers of ice to get through, but once you get through the ice, we believe that there are salty oceans there, on Enceladus and Europa.” Europa is of specific interest and the central aim is to see if there’s life there. “That’s the goal and they’re teaming up with us because together we can advance getting to that moon and getting in the ocean and exploring it.”Is there life on the moon Europa
VIDEO Interview: Steve Hall, Chief Executive, Society for Underwater Technology
.One of the things that excites me is that the technologies and techniques we’re learning on this world will be the things we end up applying in other worlds in the future as well. I’m sure your readers will be very familiar with some of these proposals for missions to Jupiter’s moon Europa, for example, and being able to put autonomous vehicles into these waters, getting under the ice, looking at the hydrothermal vent fields that we might find on Jupiter’s moons and discovering who knows what down there.That’s really an exciting thing is if you’re in your 20s or 30s
Saipem Scoops $500+ Mln EPCI Contracts
depths ranging between 400 and 600 meters to be carried out by Saipem vessels FDS and Saipem 3000.In the same region, specifically in Equatorial Guinea, Saipem has also signed a contract with Noble Energy for the offshore installation of a 70-kilometer gas pipeline connecting the Alen Platform to Punta Europa on the coast.Additional minor contracts awarded are related to the decommissioning of existing infrastructures located in the Thistle Field of the North Sea to be executed by the Saipem 7000 and two other offshore transportation and installation contracts in the Middle East and the Gulf of Mexico
WHOI Robot Takes First Known Automated Sample from Ocean
arm extended down to the precise sample location and sucked up the dirt.Billings says this level of automation will be important for NASA as they look toward developing technologies to explore ocean worlds beyond our solar system. “If we have this grand vision of sending robots to places like Europa and Enceladus [the moons of Jupiter and Saturn, respectively], they will ultimately need to work independently like this and without the assistance of a pilot,” he says.Moving forward, Camilli will continue working with Billings and colleagues at the University of Michigan, as well as researchers
Saipem Wins $100 Mln Pipeline Contract
Equatorial Guinea has awarded a $90-$100 million contract to build a 70 km subsea pipeline linking the Noble Energy operated Alen Unit to the country's Punta Europa petrochemical hub to Italian firm Saipem , the oil ministry said on Thursday.The first gas is expected to be delivered from the project early in 2021, said oil minister Gabriel Obiang Lima in a statement.(Reporting by Wendell Roelf; Editing by Muralikumar Anantharaman)
Steel Cut for 1st LNG-fueled Ship in France
, a global cruise line registered in Switzerland and based in Geneva, has held a steel-cutting ceremony for its first new-generation World-Class ship at the Chantiers de l'Atlantique shipyard in Saint-Nazaire, France.The first of five liquefied natural gas (LNG) powered cruise ships on order, MSC Europa is the first LNG ship to be built in France.On the occasion of the cutting of the first steel ceremony held in Saint-Nazaire, MSC and Chantiers de l’Atlantique unveiled a groundbreaking R&D project named PACBOAT.The project focuses on the integration of a new fuel cell technology demonstrator
