Using echolocation, dolphins will able to detect a pregnant woman's developing fetus, some experts say. Dolphins emit sounds in their environment and listen to the echoes that return — a process that helps them identify the shapes and locations of objects. Doctors use a similar technique to image a developing human baby. Both involve ultrasound — high-pitched pulses of sound above the range of human hearing. ಡಾಕ್ಸಿನ್ ಗಳು ಗರ್ಭಿಣಿ ಮಹಿಳೆಯರಿಗೆ ಹೆಚ್ಚು ಪ್ರೀತಿ ತೋರಿಸುತ್ತದೆ ಏಕೆಂದರೆ ಅವು ಅಲ್ಪಾಸೌಂಡ್ ಮೂಲಕ ಸಂವಹನ ನಡೆಸುತ್ತವೆ, ತಾಯಿಯ ಹೃದಯ ಬಡಿತದ ಜೊತೆಗೆ ಅವುಗಳು ಮಗುವಿನ ಹೃದಯ ಬಡಿತವನ್ನು ಸಹ ಕೇಳಬಹುದು . . 👆👆👆@generalknowledgeinkannada ನಮ್ಮ ಪೇಜ್ ಅನ್ನು Follow ಮಾಡಿ. ಮತ್ತು ನಮ್ಮ YOUTUBE CHANNEL ಅನ್ನು SUBSCRIBE ಮಾಡಿ .

Quick FAQs

Is this a main blog? This is a side blog, my main is @amelias-hart. To keep this blog mostly to fic updates and as a reference tool, I reblog LoZ stuff on my main, to include art and fics.

Can I draw fanart of your characters? Yes, absolutely. I should clarify. You are more than welcome to draw art based on the descriptions in my fics and the resources I put out for them. I work with other artists though for most of my character art. If you are going to use those designs, make sure you're familiar with their opinions on fanart.

What kinds of LoZ fics to you write? All of my fics are fully original legend and long form stories. My average chapter length is 3k and the shortest of my fics (not in a series) is currently drafting to be like 100 chapters.

How adult/mature are they? It ranges, but typically it's pretty tame. I don't really handle gore and explicit scenes, and I'm not a fan of dark fantasy generally as a writer. If fics are rated adult/mature, it's typically because the characters are largely adults.

Is there romance? We're on that Zelink train, absolutely! There are no explicit scenes, again, so the range here is fluff (GoS, RA) to some more mature flirting with some innuendo being about the most serious content (DAD). Maybe a more intense kissing scene once the slow burn gets through to that (MoaH).

How do you write so much? Autism baby. Got that clinical hyperfocus going.

Do I need to read your fics in a certain order? No, all of them are stand alone but they do share a linked timeline in the following: GoS -> MoaH -> RA -> CoL -> DAD (And honestly it's really just GoS and MoaH with any "serious" timeline lore connections)

What's the Convergence? To the previous point, it's referring to GoS any time it comes up. Really only a thing in MoaH and MoaH does try to explain it within the text.

Will add more as they come up. If it's not here, it's probably below. If not, send it as a reply or an ask and I'll add it!

POV: When you’re in the middle of the anchovy school. 😲⁠ 

When most people think about marine life in Monterey Bay, they think of large animals such as whales, sea lions, and pelicans. But none of these charismatic creatures would be here if not for millions of smaller animals, such as anchovies and krill.⁠ ⁠ 

Over the last decade, MBARI Senior Scientist Kelly Benoit-Bird has been studying these small, but important animals, using advanced echosounders mounted on boats and underwater robots. Kelly and her team investigate how animals respond to constantly changing environments, including how animals find dinner without becoming dinner themselves and the way group behaviors like schooling or cooperation affect predator-prey interactions.

Sound reveals giant blue whales dance with the wind to find food

Sound reveals giant blue whales dance with the wind to find food

A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious, endangered blue whales. The research team used a directional hydrophone on MBARI’s underwater observatory, integrated with other advanced technologies, to listen for the booming vocalizations of blue whales. They used these sounds to track the movements of blue whales and learned that these ocean giants respond to changes in the wind.

Along California’s Central Coast, spring and summer bring coastal upwelling. From March through July, seasonal winds push the top layer of water out to sea, allowing the cold water below to rise to the surface. The cooler, nutrient-rich water fuels blooms of tiny phytoplankton, jumpstarting the food web in Monterey Bay, from small shrimp-like krill all the way to giant whales. When the winds create an upwelling event, blue whales seek out the plumes of cooler water, where krill are most abundant. When upwelling stops, the whales move offshore into habitat that is transected by shipping lanes.

“This research and its underlying technologies are opening new windows into the complex, and beautiful, ecology of these endangered whales,” said John Ryan, a biological oceanographer at MBARI and lead author of this study. “These findings demonstrate a new resource for managers seeking ways to better protect blue whales and other species.”

The directional hydrophone is a specialized underwater microphone that records sounds and identifies the direction from which they originate. To use this technology to study blue whale movements, researchers needed to confirm that the hydrophone reliably tracked whales. This meant matching the acoustic bearings to a calling whale that was being tracked by GPS. With confidence in the acoustic methods established, the research team examined two years of acoustic tracking of the regional blue whale population.

This study built upon previous research led by MBARI Senior Scientist Kelly Benoit-Bird, which revealed that swarms of forage species — anchovies and krill — reacted to coastal upwelling. This time, researchers combined satellite and mooring data of upwelling conditions and echosounder data on krill aggregations with the acoustic tracks of foraging blue whales logged by the directional hydrophone.

“Previous work by the MBARI team found that when coastal upwelling was strongest, anchovies and krill formed dense swarms within upwelling plumes. Now, we’ve learned that blue whales track these dynamic plumes, where abundant food resources are available,” explained Ryan.

Blue whales recognize when the wind is changing their habitat and identify places where upwelling aggregates their essential food — krill. For a massive animal weighing up to 150 tonnes (165 tons), finding these dense aggregations is a matter of survival.

While scientists have long recognized that blue whales seasonally occupy Monterey Bay during the upwelling season, this research has revealed that the whales closely track the upwelling process on a very fine scale of both space (kilometers) and time (days to weeks).

“Tracking many individual wild animals simultaneously is challenging in any ecosystem. This is especially difficult in the open ocean, which is often opaque to us as human observers,” said William Oestreich, previously a graduate student at Stanford University’s Hopkins Marine Station and now a postdoctoral fellow at MBARI. “Integration of technologies to measure these whales’ sounds enabled this important discovery about how groups of predators find food in a dynamic ocean. We’re excited about the future discoveries we can make by eavesdropping on blue whales and other noisy ocean animals.”

Background

Blue whales (Balaenoptera musculus) are the largest animals on Earth, but despite their large size, scientists still have many unanswered questions about their biology and ecology. These gentle giants seasonally gather in the Monterey Bay region to feed on small shrimp-like crustaceans called krill.

Blue whales are elusive animals. They can travel large distances underwater very quickly, making them challenging to track. MBARI researchers and collaborators employed a novel technique for tracking blue whales — sound.

MBARI’s MARS (Monterey Accelerated Research System) observatory offers a platform for studying the ocean in new ways. Funded by the National Science Foundation, the cabled observatory provides continuous power and data connectivity to support a variety of instruments for scientific experiments.

In 2015, MBARI researchers installed a hydrophone, or underwater microphone, on the observatory. The trove of acoustic data from the hydrophone has provided important insights into the ocean soundscape, from the migratory and feeding behaviors of blue whales to the impact of noise from human activities.

In 2019, MBARI and the Naval Postgraduate School installed a second hydrophone on the observatory. The directional hydrophone gives the direction from which a sound originated. This information can reveal spatial patterns for sounds underwater, identifying where sounds came from. By tracking the blue whales’ B call — the most powerful and prevalent vocalization among the regional blue whale population — researchers could follow the movements of individual whales as they foraged within the region.

Researchers compared the directional hydrophone’s recordings to data logged by tags that scientists from Stanford University had previously deployed on blue whales. Validating this new acoustic tracking method opens new opportunities for simultaneously logging the movements of multiple whales. It may also enable animal-borne tag research by helping researchers find whales to tag. “The integrated suite of technologies demonstrated in this paper represents a transformative tool kit for interdisciplinary research and mesoscale ecosystem monitoring that can be deployed at scale throughout protected marine habitats. This is a game changer and brings both cetacean biology and biological oceanography to the next level,” said Jeremy Goldbogen, an associate professor at Stanford University’s Hopkins Marine Station and a coauthor of the study.

This new methodology has implications not only for understanding how whales interact with their environment and one another but also for advancing management and conservation.

Despite protections, blue whales remain endangered, primarily from the risk of collisions with ships. This study showed that blue whales in Monterey Bay National Marine Sanctuary regularly occupy habitat transected by shipping lanes. Acoustic tracking of whales may provide real-time information for resource managers to mitigate risk, for example, through vessel speed reduction or rerouting during critical periods. “These kinds of integrated tools could allow us to spatially and temporally monitor, and eventually even predict, ephemeral biological hotspots. This promises to be a watershed advancement in the adaptive management of risks for protected and endangered species,” said Brandon Southall, president and senior scientist for Southall Environmental Associates Inc. and a coauthor of the research study.

Support for this research was provided by the David and Lucile Packard Foundation. The National Science Foundation funded the installation and maintenance of the MARS cabled observatory through awards 0739828 and 1114794. Directional acoustic processing work was supported by the Office of Naval Research, Code 32. Tag work was funded in part by the National Science Foundation (IOS-1656676), the Office of Naval Research (N000141612477), and a Terman Fellowship from Stanford University.

Researchers in Antarctica to help safeguard vital krill stocks - Technology Org

New Post has been published on https://thedigitalinsider.com/researchers-in-antarctica-to-help-safeguard-vital-krill-stocks-technology-org/

Researchers in Antarctica to help safeguard vital krill stocks - Technology Org

The University of Southampton is leading an expedition to the Antarctic Peninsula to survey Antarctic krill and the baleen whales that feed upon them.

The team, who departed the UK a fortnight ago, are travelling to the remote region on a yacht to tag the whales and survey their main source of food – krill, a small shrimp-like crustacean.

Their expedition will provide data to assess whether the current fishery management framework is sufficient to safeguard krill stocks, which underpin the unique Southern Ocean ecosystem.

“The risk is that fishing becomes concentrated in krill-rich predator feeding spots and then depletes them, leaving nothing behind for the marine animals that rely on them to survive,” says Dr Ryan Reisinger from the University of Southampton, who is leading the expedition.

Antarctic krill are one of the most abundant animals on earth and are a major food source for many predators, including fish, penguins, seals and baleen whales. Antarctic krill also send carbon to the deep ocean through the sinking of their faeces and by moulting their exoskeletons. The small crustaceans are the focus of a commercial fishery and are being caught at an increasing rate to be processed into feed for fish farms (e.g. salmon) and oils for nutritional supplements.

At the same time, populations of baleen whales, a major consumer of krill, are in recovery. Fin whales – the second largest baleen whale after the blue whale, had been hunted to near extinction. Now they are growing in number, returning to historic feeding grounds, and finding themselves in competition with fishing vessels.

The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is the international body which sets limits on how much Antarctic krill can be caught, where and when. These catch limits are measured in thousands of tonnes across vast swathes of ocean, but krill are particularly concentrated in smaller shelf areas close to land which are frequented by both predators and fishing vessels.

To address this mismatch in scales, CCAMLR plans to implement finer scale management procedures. To inform this, the researchers from the University of Southampton, the British Antarctic Survey, the University of California Santa Cruz, and the Scottish Association for Marine Science are collecting data to better understand the distribution of foraging fin whales, Antarctic krill and fishing vessels.

Team members from the University of California Santa Cruz are fitting two different types of tags to fin whales. CATS tags provide short-term detailed data, monitoring swimming speed, direction, body orientation and more, while LIMPET tags provide longer-term information on the location and behaviour of the whales.

Dr Reisinger adds: “Tagging whales helps us to understand in far greater detail where and how whales feed on krill, information that is essential for us to manage and conserve Southern Ocean ecosystems. We know surprisingly little about how the largest whales – including fin whales – behave in Antarctica”.

The researchers are using echosounders – a type of sonar – to locate and measure swarms of krill. These are fitted to the bottom of the research vessel and a new type of autonomous vehicle called an ImpYak®. Developed by the Scottish Association for Marine Science, this is essentially a remote-controlled, impeller-driven kayak which will be used to survey near-shore areas that research vessels can’t reach.

Three University of Southampton PhD students are on the expedition, funded by the INSPIRE programme. Amy Feakes, one of the PhD students, said: “Being part of this research cruise has been an incredible learning experience – from collecting data for my PhD to understanding the planning that goes into a research cruise. Working in this challenging environment and with new equipment and technology has given me some new skills which I can hopefully continue to use throughout my PhD.”

The data collected from this fieldwork will be combined with information on fishing vessel activity provided by CCAMLR and Global Fishing Watch to model overlap between krill, whales and fisheries, to provide forecasts which could be used for finer scale, more dynamic fisheries management.

Dr Sophie Fielding, an ecologist at the British Antarctic Survey, said: “Antarctic krill play a central role in the Antarctic marine ecosystem. Making measurements of krill (prey) alongside their predators (whales) in near-shore areas is technically challenging and will provide new insights into controls on swarm behaviour and distribution.”

The project is funded by the UK Government through Darwin Plus.
