The remarkable secrets of a new #octopus garden hosting an estimated 6,000 brooding females are revealed in a new study. Warmth from hydrothermal springs is found to play a key role by raising metabolic rates, speeding embryonic development, and likely increasing reproductive success, with brood times for females up to 3 or 4 times faster than expected for abyssal octopods. https://lnkd.in/eJht4BmU This is a nice demonstration of how a suite of non-invasive #subsea #technologies can reveal and chronicle patterns of #biodiversity richness in the #deepsea. With tens of thousands of seamounts scattered across the world ocean, many of them uncharted, this begs the question how many treasures such as this remain undiscovered? https://lnkd.in/e-TsCBeW It is crucial that the implementation of #30by30 representatively protects marine #biodiversity where it flourishes. Seamounts are known to be hotspots of marine life but the vast majority of them and the global ocean are unprotected. "The sea floor over 2 km deep covers roughly 60% of Earth’s surface and outside the ocean science community is generally thought of as a vast, largely homogeneous frontier. Vast indeed, efforts continue to map large areas where we have only grainy views of the seafloor and scant information concerning potentially vital heterogeneities and anomalies—warm spots, seamounts, vents, and others. Most of these “island” habitats remain unseen and unknown, including their potentially large influence for deep-sea populations and broad indirect influence of the structure and function of deep-sea #ecosystems. Precautionary stewardship of poorly known abyssal resources and continued exploration of unknown deep-sea environments are essential to discover and protect habitats that may play disproportionately large roles in the dynamics of populations and the biodiversity of deep-sea ecosystems." #marineprotection #marinescience #sdg14

🌕🌚🌝 Today’s total solar eclipse gives oceanographers the unique opportunity to study the largest animal migration on Earth! Every night, billions of zooplankton, squid and fish ascend from the ocean twilight zone to feed near the surface, then descend back to the safety of darkness before daybreak. So what happens when the sun goes down earlier (or comes up later) than usual? If it’s anything like what researchers observed with Ocean Observatories Initiative instruments in the North Pacific in 2017, animals will start their journey to the surface whenever the sunlight starts to wane. ⁉️ Are you noticing any strange behavior in the animal world today? 📸: Echogram showing animal migration, as measured from the OOI Oregon Offshore midwater platform. The dark red line shows the acoustic return of solar radiation from the sea surface; other red and bright green colors are acoustic waves scattering off migrating zooplankton. Times of sunset and sunrise are noted by black vertical lines. Figure from Barth, J.A., et al. 2018.

It is high time we start bringing appropriate simple life forms to Mars to initiate the long process of its terraforming:

New CPO-funded research in the journal Nature shows marine heatwave effects on predator habitats. It demonstrates the complexity of marine heatwave impacts using modeling techniques and observations focused on 14 different species in the Northeastern Pacific. https://lnkd.in/ecYN5rys

Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass.

Indicator of the week: Continuous noise This indicator evaluates sound pressure levels in the Baltic Sea. Good status is achieved when the sound pressure indicator is below the 20% spatial threshold for fish (125 Hz) and marine mammals (500 Hz) for all months in 2018. Two indicator variants were evaluated: the median total sound pressure level, which was below the 20% threshold for all fish and marine mammals, while the median excess noise was below the threshold for marine mammals but exceeded it for fish communication in 9 out of 17 units. The indicator will be further developed with region-specific thresholds and species-specific values, aiming for improvements by HOLAS 4. Properties of underwater sound are extremely diverse and sound can be classified in many different ways. A common division is into two categories as natural and anthropogenic where the first encompasses all sounds that are produced by either animals or geophysical processes, while the second is produced by human activities. https://buff.ly/4c7G8Dx #HELCOMindicators #BSAP #HOLAS3

Terraforming Mars is a big challenge, but some #scientists think microbes could help. Introducing certain types of bacteria, may help to thicken Mars' thin atmosphere and make its soil more fertile for plants. 🌱 Of course, the introduction of microbes to Mars is not without its risks and ethical considerations. We must carefully evaluate the potential ecological impact and ensure that any microbial species introduced are thoroughly studied and understood beforehand. Additionally, stringent protocols must be in place to prevent contamination and preserve the integrity of Martian ecosystems, should they exist. #SpaceExploration #Space Source: It’s Cosmoknowledge
