A total of 41 humpback whales (Megaptera novaeangliae) have died in the waters off Maine to North Carolina, said the National Oceanic and Atmospheric Administration. Twenty-six died last year, far higher than the average annual number of humpback whales for the area—just 14. So far this year, 15 have already washed up dead. "The increased numbers of mortalities have triggered the declaration of an unusual mortality event, or UME, for humpback whales along the Atlantic Coast," said Mendy Garron, stranding coordinator at the NOAA Fisheries Greater Atlantic Region. A UME is issued whenever a stranding is "unexpected, involves a significant dieoff of any marine mammal population, and demands immediate response," she told reporters. Animal autopsies—known as necropsies—have been performed on 20 whales. Ten of the marine mammals showed acute signs of blunt force trauma or large propeller cuts from colliding with ships or boats, suggesting this was the likely cause of death. The other 10 had no such obvious signs, and researchers are continuing tests to find out what other factors could have contributed to their demise. "Whales tested to date have had no evidence of infectious disease," said Garron. Researchers stressed they have yet to uncover the cause of the unusual spike in deaths. "The answer is really unknown," said Greg Silber, coordinator of recovery activities for large whales with the NOAA Fisheries Office of Protected Resources. There is no known spike in vessel traffic in the area, but humpback whales move around in search of prey, which could bring them closer to shore, he added. Humpback whales grow to between 48 and 62 feet (15-19 meters), weigh 40 tons, and are known for their haunting songs that travel great distances underwater. Most humpback whales are no longer considered an endangered species, after that designation was lifted in 2016 due to a rebounding population. There are more than 10,000 humpback whales in the North Atlantic Ocean. But there are 14 distinct populations of the whales, five of which are still endangered, including those in the Arabian Sea, Cape Verde Islands, northwestern Africa, the Western North Pacific and Central America. An international moratorium on hunting them was established in 1982 and remains in place. Unusual die-offs of humpback whales in the Atlantic Ocean were also reported in 2003, 2005 and 2006, NOAA said. The cause of those deaths were undetermined.

Marine experts working in the Gulf of Mexico report that the mass die-off of dolphins in the coast region has steadily declined five years since the Deepwater Horizon oil spill occurred in 2010. Research biologist Jenny Litz from the National Marine Fisheries Service (NMFS) announced on Friday, Oct. 16, that the number of dolphin mortalities in the Gulf has dropped this year since reaching its peak between 2010 and 2014. When the BP-owned Deepwater Horizon oil rig exploded in April of 2010, it killed 11 people working on the offshore platform and spilled around 4.9 million barrels' worth of unprocessed oil into the surrounding ocean before it was finally sealed five months later. Despite the mishap, BP refuses to be held accountable for the die-off, asserting that the frequent deaths of marine animals in the area in the past were caused by the spread of bacterial diseases in the region. In response to a report by the National Oceanic and Atmospheric Administration (NOAA), BP said it is important to consider that the mass die-offs of dolphins in the Gulf are not unusual. The London-based company pointed out that while the Unusual Mortality Event (UME) overlapped in certain areas affected by the oil spill, there is no indication that it was caused related to the mishap. NOAA scientists, however, disagree with BP's stance, stating that the population of dolphins in the region has been prone to such mass die-offs in the past, but it has never been occurred for as long as it did following the oil spill. They said the accident has affected a wide range of marine mammals, particularly their calves. "No feasible alternatives remain that can reasonably explain the timing, location and nature of this increase in death," Stephanie Venn-Watson, NOAA scientist and one of the co-authors of the report, said. Die-offs of Marine Animals in the Gulf According to reports, the average number of animal deaths in the Gulf of Mexico typically reaches around 74 individual dolphins each year. This number, however, grew to about 248 marine mammals during the five-year span following the oil spill. NMFS estimates state that there have already been 1,433 dolphins and whales killed in the aftermath of the 2010 oil spill. Out of this number, 1,246 (87 percent) of those affected happened to be bottlenose dolphins. The adverse effects of the oil spill on the environment were far reaching, but populations of dolphins have proved to be especially sensitive to waters damaged by the accident. The NOAA explained that many of the dolphin species in the Gulf are shallow-water or coastal-dwelling animals that appear to stay in specific areas of the waters, making it possible for the sea creatures not to abandon even a severely damaged habitat. Marine experts believe that even though there has been progress, the reliance of dolphins on the Gulf as a habitat means that there is still much work to be done in order to make the waters safer. In May, the NOAA said that similar to what has been observed in the Exxon Valdez oil spill, the breakdown of oil products can affect the food chain, build up in the tissues of creatures, produce cascading effects on ecosystems as well as impact populations of wildlife for many years to come.

Bottlenose Dolphin - Tursiops truncatus A dolphin surfs the wake of a research boat on the Banana River - near the Kennedy Space Center. Credit: Public Domain (Phys.org)—A team of researchers with members from institutions in Australia, the U.S. and the U.K. has found evidence that suggests increased dolphin familiarity with humans has led to an increase in injury and death to the marine mammals. In their paper published in the journal Royal Society Open Science, the team describes their study and why they believe current trends could lead to a drop in the dolphin population along the Florida coast. In a related paper in the same journal, a team of researchers affiliated with several institutions in Australia reports on an unusual mortality event (UME) involving cases of morbillivirus in several types of dolphins and offer a theory regarding why it may have occurred. In the first study, the researchers used a database that stored information describing interactions between humans and dolphins near Sarasota Bay in Florida over the years 1993 to 2014. In all, they studied data on 32,000 dolphin sightings that involved approximately 1,000 dolphins. Dolphins in the database were classified as being "conditioned" if they behaved in ways that suggested they actively sought out humans for food. They noted that during the initial years of the study, only 25 of the dolphins were conditioned—that number jumped to 190 by the final study year, suggesting a trend toward more dolphins becoming conditioned. The researchers also found that those dolphins defined as conditioned experienced higher mortality rates than other dolphins, further suggesting that interactions with humans were causing some to be killed. The researchers noted this might be due to dolphins being struck by high-speed boats or propellers or by becoming entangled in nets. They noted also that 75 of the dolphins under study showed signs of human-related injuries. In the second story, the research team in Australia found that a UME had occurred off the South Australia coast in 2013 involving multiple types of dolphins being infected with the morbillivirus—a relative of the virus that causes measles in humans. Approximately 50 dolphins died during the event, though the researchers do not know how much of an impact it had on the population as a whole. They noted that the UME occurred during a period of increased water temperatures and a diatom bloom that also coincided with a large fish die-off, which suggests the likely cause of the unusual event was the increase in marine temperature. More information: 1. Fredrik Christiansen et al. Food provisioning increases the risk of injury in a long-lived marine top predator, Royal Society Open Science (2016). DOI: 10.1098/rsos.160560 Abstract Food provisioning of wildlife is a major concern for management and conservation agencies worldwide because it encourages unnatural behaviours in wild animals and increases each individual's risk for injury and death. Here we investigate the contributing factors and potential fitness consequences of a recent increase in the frequency of human interactions with common bottlenose dolphins (Tursiops truncatus) in Sarasota Bay, Florida. A rising proportion of the local long-term resident dolphin community is becoming conditioned to human interactions through direct and indirect food provisioning. We investigate variables that are affecting conditioning and if the presence of human-induced injuries is higher for conditioned versus unconditioned dolphins. Using the most comprehensive long-term dataset available for a free-ranging bottlenose dolphin population (more than 45 years; more than 32 000 dolphin group sightings; more than 1100 individuals), we found that the association with already conditioned animals strongly affected the probability of dolphins becoming conditioned to human interactions, confirming earlier findings that conditioning is partly a learned behaviour. More importantly, we found that conditioned dolphins were more likely to be injured by human interactions when compared with unconditioned animals. This is alarming, as conditioning could lead to a decrease in survival, which could have population-level consequences. We did not find a significant relationship between human exposure or natural prey availability and the probability of dolphins becoming conditioned. This could be due to low sample size or insufficient spatio-temporal resolution in the available data. Our findings show that wildlife provisioning may lead to a decrease in survival, which could ultimately affect population dynamics. 2. C. M. Kemper et al. Morbillivirus-associated unusual mortality event in South Australian bottlenose dolphins is largest reported for the Southern Hemisphere, Royal Society Open Science (2016). DOI: 10.1098/rsos.160838 Abstract Cases of morbillivirus have been recorded in the Southern Hemisphere but have not been linked to significant marine mammal mortality. Post-mortems were conducted on 58 carcasses (44 Indo-Pacific bottlenose dolphins, two common bottlenose dolphins, 12 short-beaked common dolphins) from South Australia during 2005–2013, including an unusual mortality event (UME) in St Vincent Gulf Bioregion (SVG) during 2013. Diagnostic pathology, circumstance of death, body condition, age and stomach contents were documented for Indo-Pacific bottlenose dolphins. At least 50 dolphins died during the UME, 41 were Indo-Pacific bottlenose dolphins and most were young. The UME lasted about seven months and had two peaks, the first being the largest. Effect on the population is unknown. Diagnostic testing for morbillivirus was conducted on 57 carcasses, with evidence for infection in all species during 2011–2013. All tested UME bottlenose dolphins were positive for cetacean morbillivirus (CeMV), and the pathology included interstitial pneumonia, lymphoid depletion and syncytia. Concurrent pathologies, including lung parasite and fungal infections, and severe cutaneous bruising were observed in many dolphins. The event coincided with elevated water temperatures, a diatom bloom and significant fish die-offs. We conclude that the cause for the UME was multifactorial and that CeMV was a major contributor.

We analyzed 20 years of AVISO data set to detect and characterize long-lived eddies, which stay coherent more than 6 months, in the eastern Mediterranean Sea. In order to process the coarse gridded ( 1/8°) AVISO geostrophic velocity fields, we optimized a geometrical eddy detection algorithm. Our main contribution was to implement a new procedure based on the computation of the Local and Normalized Angular Momentum (LNAM) to identify the positions of the eddy centers and to follow their Lagrangian trajectories. We verify on two mesoscale anticyclones, sampled during the EGYPT campaign in 2006, that our methodology provides a correct estimation of the eddy centers and their characteristic radius corresponding to the maximal tangential velocity. Our analysis reveals the dominance of anticyclones among the long-lived eddies. This cyclone-anticyclone asymmetry appears to be much more pronounced in eastern Mediterranean Sea than in the global ocean. Then we focus our study on the formation areas of long-lived eddies. We confirm that the generations of the Ierapetra and the Pelops anticyclones are recurrent and correlated to the Etesian wind forcing. We also provide some evidence that the smaller cyclonic eddies formed at the southwest of Crete may also be induced by the same wind forcing. On the other hand, the generation of long-lived eddies along the Libyo-Egyptian coast are not correlated to the local wind-stress curl but surprisingly, their initial formation points follow the Herodotus Trough bathymetry. Moreover, we identify a new formation area, not discussed before, along the curved shelf off Benghazi. © 2014. American Geophysical Union. All Rights Reserved.

Modeling the flow around a deformable and moving surface is required to calculate the forces exerted by a swimming or flying animal on the surrounding fluid. Assuming that viscosity plays a minor role, linear potential models can be used. These models derived from unsteady airfoil theory are usually divided in two categories depending on the aspect ratio of the moving surface: for small aspect ratios, slender-body theory applies while for large aspect ratios two-dimensional or lifting-line theory is used. This paper aims at presenting these models with a unified approach. These potential models being analytical, they allow fast computations and can therefore be used for optimization or control. © 2009 Society for Experimental Mechanics.

TUBITAK UME Temperature Laboratory initiated a new study which focuses on the construction of a tin freezing-point cell as a primary temperature standard. The design is an open-cell type similar to the National Institute of Standards and Technology design. With this aim, a brand new vacuum and filling line employing an oil diffusion pump and two cold traps (liquid nitrogen and dry ice) was set-up. The graphite parts (crucible, thermometer well, etc.) have been baked at high temperature under vacuum. Each cell was filled with approximately 1 kg of high-purity tin (99.9999 %) in a three-zone furnace. Then several melting and freezing curves were obtained to assess the quality of the home-made cell, and also the new cell was compared with the existing reference cell of the laboratory. The results obtained are very close to the reference cell of UME, indicating that the method used for fabrication was promising and satisfactory and also seems to meet the requirements to have a primary level temperature standard. © 2015, Springer Science+Business Media New York.

Construction of a physical model for the grand piano implies complex and multidimensional phenomena. We present a model of piano strings coupled to a soundboard, and its numerical approximation. Measurements on piano strings and bridge show phantom partials and a time precursor that both cannot be explained by the linear scalar string model. A classical model of nonlinear strings has been written by Morse & Ingard, it implies to consider the longitudinal displacement as well as the standard transversal displacement of the string, in a nonlinear coupled system. Various approximate (polynomial) models have been written from this one, by expanding the nonlinearity (a square root term) around the rest position of the string. We provide a mathematical justification of the most used model. Transmission of the string motion to the rest of the structure is essential from the acoustical point of view. We use a modal approach for the soundboard, and we write a nonstandard reciprocal coupling condition between strings and soundboard at the bridge. Numerical approximation of such a nonlinear, multidimensional and coupled problem is a difficult issue. We use an energy approach to achieve stability, which leads to an innovating implicit numerical scheme.
