Falklands, Freshwater Project for the Islands community, farming and MPC A Freshwater Project for the Falkland Islands funded by UK’s Darwin Plus program plus Falklands’ Government and led by SAERI, South Atlantic Environmental Research Institute in partnership with UK’s Centre for Ecology & Hydrology (UKCEH) has been working intensely in the terrestrial ecosystems of the archipelago, given its sensitivity in land use and climate change. This 2-year project recognizes these challenges, and given farming is the very fabric of the FI community, a growing desire exists for data driven solutions to facilitate innovation and sustainable land management and climate change adaptation. This means bringing together existing data and data tools plus harnessing technological solutions. The high-level research aims are to: a) Use freely available Landsat and Sentinel satellite imagery to assess past (last 30 y) and present freshwater dynamics (surface water extent and soil moisture (e.g. Normalized Difference Moisture Index, Soil Water Index), and b) Model future scenarios of freshwater dynamics using a number of data-driven gridded models. According to a SAERI report, freshwater is essential to life in the Falkland Islands, supporting farming, wildlife, and the wider environment. In recent years, however, many local communities have noticed ongoing drying and are increasingly concerned about changes in freshwater availability. The...

Scientists Just Discovered a Hidden Freshwater World Beneath the Great Salt Lake Scientists found extensive freshwater beneath the Great Salt Lake, offering new insights into groundwater flow and potential environmental solutions. A new study is shedding light on what could be a vast underground freshwater reservoir beneath the Great Salt Lake. Researchers used airborne electromagnetic (AEM) surveys to image geologic structures below Farmington Bay and Antelope Island along the lake’s southeastern shore. Geophysicists at the University of Utah analyzed the data and found that freshwater saturates sediments beneath the lake’s highly salty surface at depths of 3 to 4 kilometers (about 1.9 to 2.5 miles, or 10,000 to 13,000 feet). The helicopter-based survey followed earlier observations of freshwater rising under pressure at several locations on the exposed lakebed in Farmington Bay, forming unusual mounds covered in dense phragmites reeds. According to lead author Michael Zhdanov, the study is the first to show that AEM methods can detect freshwater beneath the thin, conductive saltwater layer at the lake’s surface. His team also mapped how far the freshwater extends beneath Farmington Bay and estimated the depth of water-saturated sediments by identifying the underlying basement structure. Mapping Depth, Volume, and Extent “We were able to answer the question of how deep this potential reservoir is...

Fracture-based grasping: dynamic impact enables predictable robotic anchoring to freshwater ice The icy worlds of Enceladus and Europa represent two compelling science targets in the outer solar system. With subsurface liquid water oceans1,2 and active thermal energy sources3,4,5, these small moons represent some of the best places in the solar system to search for extant extraterrestrial life. Enceladus is particularly compelling for its active plumes6, depositing material onto the surface, and potentially providing a natural access point to the subsurface ocean. Recent findings reinforce the potential for habitability in the ocean of Enceladus: evidence suggests that the ocean is warm and briny, contains simple hydrocarbons and methane4,7 and contains nearly all the basic elements required for life, including carbon, hydrogen, nitrogen, oxygen, and phosphorus7,8,9. Enceladus poses unique challenges for robotic explorers, however. The gravitational acceleration at the surface of Enceladus is low (0.113 m/s210, or 1% Earth gravity). For robotic climbers to descend the active vents and sample the ocean directly, a vehicle must be able to withstand the force of the plume ejecta, which may far exceed the weight of the vehicle itself11. As a result, a robotic climbing vehicle for Enceladus would likely need to (i) form a strong attachment to the icy terrain and (ii) do so with...

World's Freshwater Fish in Crisis, U.N. Report Finds Over the last half century, populations of migrating freshwater fish have dropped by 81 percent, according to a stark new U.N. report. Hundreds of species of fish, which together sustain hundreds of millions of people, are imperiled by warming, pollution, dams, and intensive fishing, according to the report, launched at a U.N. meeting on migratory wildlife now underway in Brazil. As threats mount, populations of freshwater animals are declining faster than populations of animals on land or sea. With more than 250 rivers and lakes worldwide crossing international borders, conservationists say that countries must work together to protect imperiled fish. “Rivers don’t recognize borders — and neither do the fish that depend on them,” said coauthor Michele Thieme, deputy lead of freshwater for World Wildlife Fund U.S. The dorado catfish of the Amazon basin offers a prime example. A bottom dweller that grows to more than six feet long, the dorado catfish undertakes the longest migration of any freshwater fish in the world. It travels 7,000 miles over the course of its life, from its spawning grounds in the Peruvian Andes to its feeding grounds at the mouth of the Amazon River in Brazil, and back. Increasingly, it is threatened...

Freshwater fish populations plunge 81% as river migrations collapse The Global Assessment of Migratory Freshwater Fishes, released at the CMS 15th Meeting of the Conference of the Parties (COP15) in Brazil, finds that migratory freshwater fish are among the most threatened species worldwide. These fish are critical for maintaining healthy rivers, supporting major inland fisheries, and providing food and livelihoods for hundreds of millions of people. Hundreds of Migratory Fish Species Need Global Protection The assessment highlights hundreds of migratory fish species that require coordinated international action. It provides strong evidence that fish relying on connected rivers across national borders are declining quickly due to dam construction, habitat fragmentation, pollution, overfishing, and climate-related ecosystem changes. In total, 325 migratory freshwater fish species have been identified as candidates for international conservation efforts, pointing to a largely overlooked biodiversity crisis across shared river systems. A regional breakdown of the 325 migratory freshwater fish species deemed candidates for international protection (beyond the 24 already listed) under the Convention's Appendices I (species requiring strict protection) and II (species needing international cooperation): Asia: 205 South America: 55 Africa: 42 Europe: 50 North America: 32 (The total adds to more than 325 because some species occur on multiple continents.)

Migratory Freshwater Fish Populations Are Collapsing Across The World. What Can Be Done To Save Them? When it comes to conservation efforts, there is a widespread and disproportionate bias towards the protection of charismatic species. These are animals that people deem more “cute” or impressive (think pandas or tigers), or even more human-like in appearance or behavior. But this bias means that less funding, research, and protection is extended to species that do not fall within this perspective. Migratory freshwater fish, such as salmon, sturgeon, the European eel, the Mekong giant catfish, and the Amazonian Dorado catfish are among them. Although freshwater fish are a vital factor for global food security, being the primary source of protein for over 200 million people across the world, these incredibly diverse migratory fish are faced by considerable growing threats. In 2011, the CMS examined the status of this group but limited their gaze to around 3,000 species. Since then, the International Union for Conservation of Nature’s (IUCN) Red List, an inventory of the global conservation status and extinction risk for animal species, has expanded its own assessment to nearly 15,000 species, allowing for far great insights into their status and current trends. This latest CMS report represents an update to the 2011 review using this work. The report identified...

Freshwater fish are vanishing from the world's rivers When people think of epic animal migrations, they picture wildebeest thundering across the Serengeti or birds crossing oceans. But some of the longest, most important migrations on Earth are happening underwater, in rivers – and a big new UN-backed assessment says they’re collapsing fast. The report, called the Global Assessment of Migratory Freshwater Fishes, is being launched by the UN’s Convention on the Conservation of Migratory Species (CMS) at COP15 in Brazil. The report is basically a loud wake-up call about a crisis that’s been easy to ignore because it unfolds beneath the surface. Migratory freshwater fish are in serious trouble, and protecting them requires countries to manage rivers like connected systems, not like separate national pieces. Significance beyond biodiversity Migratory freshwater fish aren’t just a niche conservation concern. They keep rivers functioning. They move nutrients. They support food webs. And they underpin major inland fisheries that feed and support hundreds of millions of people. Many of these species aren’t “local” in the way we often imagine river fish. Their life cycles depend on long, uninterrupted corridors – routes between spawning grounds, feeding areas, and nursery floodplains that can span thousands of kilometers and cross multiple borders. That’s also what...

Multi-phase retreat of the Laurentide Ice Sheet and associated freshwater release from Hudson Bay during the last deglaciation Large variations in ice-sheet extent and associated changes in meltwater discharge profoundly modulated regional climate and ocean circulation during the last deglaciation. Understanding these ice–ocean interactions is therefore essential for assessing the impacts of ongoing and future cryospheric change1,2. The most prominent episode of freshwater perturbation in the last 10,000 years is the ~ 160-yr cold anomaly at 8.2 ka BP3,4, widely attributed to a slowdown of the Atlantic Meridional Overturning Circulation (AMOC) following the input of large volumes of freshwater to the North Atlantic through Hudson Bay and Strait5,6,7,8,9,10,11. This rise in freshwater delivery to the ocean has been attributed to the drainage of glacial Lake Agassiz–Ojibway (LAO)12,13,14 which formed along the southern margin of the Laurentide Ice Sheet (LIS) during its northward retreat (Fig. 1). LAO was separated from the ocean by the Hudson Bay Ice Saddle (HBIS) that collapsed sometime between 8.6 and 8.1 ka15,16. Although LAO drainage undoubtedly supplied freshwater to the ocean, its role as the primary forcing mechanism for the 8.2 ka AMOC slowdown has been questioned, particularly with respect to the magnitude and duration of the freshwater pulse required to sustain the observed climate anomaly. In this context, several modelling studies propose alternative...

Migratory Freshwater Fish Numbers Are Close To Collapse, UN Report Warns Migratory freshwater fish populations crucial to river health and sustaining the livelihoods of millions of people are in freefall and risk collapse, a major UN assessment warned Tuesday. Habitat destruction, overfishing and water pollution from the Amazon to the Danube threaten the very survival of hundreds of species whose epic voyages along the world's great rivers go largely unnoticed. Freshwater fish face multiple threats, said the report published at the opening of the COP15 summit on migratory species in Brazil, making them "among the most imperiled vertebrates". Populations of Mekong giant catfish, European eel and various sturgeon species are among those that have been decimated in recent decades due to man-made pressures that include the construction of dams and harvest for caviar. Some – including the Chinese paddlefish – have already been declared extinct, while others are functionally reliant on captive breeding stock and reintroductions to support wild populations. According to conservation group WWF, migratory freshwater fish numbers have plunged some 81 percent since 1970. These fish – a vital protein source for people and animals around the globe – require unimpeded passage to move between spawning and feeding grounds, which can span across borders. This means international cooperation is...

CMS COP15: Migratory freshwater fish populations in peril as 81% declined in 50 years Migratory freshwater fish populations across the world have declined by nearly 81 per cent since the 1970s and roughly 97 per cent of the 58 listed migratory fish species under the Convention of Migratory Species (CMS) are threatened with extinction. These fish species, comprising of fresh and salt-water species, are rapidly collapsing, putting ecosystems at risks and threatening fisheries and livelihoods of millions of people worldwide. These findings were revealed in a report launched on March 24 at the Convention on the Conservation of Migratory Species’ COP15 in Brazil and is a comprehensive update to a 2011 review. The Global Assessment of Migratory Freshwater Fishes identifies 325 species requiring coordinated international conservation action due to declines driven by dams, habitat fragmentation, pollution, overfishing, and climate change, the report said. Of these species identified under the Convention’s Appendices I (species requiring strict protection) and II (species needing international cooperation), 205 were recorded in Asia, 55 in South America and 42 in Africa. Europe and North America documented 50 and 32 species respectively. The total amounts to over 323 as some species are found on multiple continents. Of the candidates, 136 species are categorised as threatened (Critically Endangered, Endangered, or Vulnerable) or...

Global Collapse of Migratory Freshwater Fish Drives Calls for Transboundary Cooperation Getting your Trinity Audio player ready... KEY POINTS: Migratory freshwater fish populations have declined 81 percent globally since 1970. 97 percent of listed migratory fish species are threatened with extinction, with hundreds more newly identified as at risk. Weak international cooperation — despite hundreds of rivers and lakes crossing borders worldwide — is a barrier to protecting species and restoring ecosystems. Migratory freshwater fish populations have declined by 81 percent worldwide since 1970, a collapse that underscores the urgent need for coordinated river and lake management across national borders, the United Nations warns. A report published today — the first global review of migratory freshwater fish in 15 years — greatly expands the number of assessed species, from 3,000 to roughly 15,000. Researchers identified 325 freshwater fish species with significant ecological, economic, and cultural value as in need of protection. They join the 97 percent of migratory fish species already listed under the Convention on the Conservation of Migratory Species of Wild Animals (CMS) that are currently threatened with extinction. “By aligning science, policy, and international cooperation, governments can safeguard the world’s remaining great freshwater fish migrations and the communities and ecosystems that depend on them,” Amy Fraenkel, the CMS...
