Shallow marine sedimentation within an active margin basin, James Ross Island, Antarctica

first_imgThe Santa Marta Formation exposed on northern James Ross Island, Antarctica, represents shallow marine shelf sedimentation within an active margin basin. The formation is approximately 1000 m thick, is of uppermost Santonian to Campanian age and represents part of a 5000–6000 m thick sedimentary sequence forming the Larsen Basin. The Larsen Basin represents either a back-arc basin, or a half-graben basin, developed on the extending margin of the Weddell Sea. Twelve sedimentary facies have been recognised, which can be subdivided into two groups: those which are controlled by shelf processes and those which are related to active arc volcanism. Background shelf processes include fair-weather suspension sedimentation, storm sands and rare tidal current reworking. Active arc processes include direct settling of airfall detritus and rapid resedimentation of volcaniclastic detritus by sandy debris-flows and both high- and low-concentration turbidity currents. In addition sheet conglomerates represent debris flows that evolved from syn-sedimentary slumps. Two facies associations representing a mid to outer shelf and an inner shelf depositional setting respectively can be distinguished, with an apparent regression in the ?mid to late Campanian.last_img read more

Dead or alive, night or day: how do albatrosses catch squid?

first_imgFor many albatross species squid are important prey. Whether albatrosses depend on scavenging (e.g. of vomit from cetaceans, post-spawning die-offs or fishery waste) or on live-capture of squid (e.g. via diel vertical migrations in association with aggregations of squid prey) is controversial. This review of the nature of interactions between squid and the four species of albatross breeding at South Georgia uses data on the foraging range, methods and timing of feeding of the albatrosses in relation to the size, distribution, buoyancy characteristics (floaters or sinkers), bioluminescence and prey of the squid and access to fishery waste. We conclude that most evidence for scavenging needs critical re-evaluation; nevertheless, whereas wandering albatrosses and possibly light-mantled sooty albatrosses probably depend significantly on scavenged squid, black-browed and especially grey-headed albatrosses are unlikely to do so.last_img read more

Body and resource size at the land–sea interface

first_imgBody size in animals varies with many parameters, amongst them taxonomic affiliation, lifestyle and ambient environment oxygen levels. Size has considerable implication to possibilities for animals; for example, parasites need to be small and top predators large. Body size and resource requirements (shell size) were investigated across the land–sea interface in hermit crabs (Crustacea: Malacostraca: Decapoda) and snails (Mollusca: Gastropoda: Prosobranchia). These are two of the few taxa to occur in the sea, on the shore and on land as residents. Both taxa are also appropriate for such an analysis as they are abundant, speciose, cohabit the same environments and are linked—gastropod shells are a critical resource to hermit crabs. Both the maximum and mean sizes of hermit crab species showed parabolic relationships with shore height, decreasing from the sublittoral and supralittoral to the eulittoral. Average maximum size of gastropods exhibited a similar intertidal minimum although variability was high. It is suggested that this pattern is robust: not only did two distantly related taxa show the same pattern, but neither region nor site contributed significantly to total variability. The mass of resources (gastropod shells) used by hermit crabs, however, showed a converse pattern. The smallest shells (relative to hermit crab body size) were used in the sublittoral and supralittoral. Response to environmental stress and predation pressure are offered as two alternate theories to explain the observed body dwarfism and resource gigantism in the intertidal zone.last_img read more

Speech: Women Mean Business speech

first_imgGood morning.This is a really important event.Not just because if we get the right environment and the right support we can have 1.1 billion more women entrepreneurs and £95 billion added to the UK economy by 2025.Not just because the #metoo movement is more than just a statement of shared experience that is shouting for inclusion, but today is important for another reason too.You are going to be hearing from some big names and some amazing business leaders today, but it is also important to think about those leaders that you won’t hear from today and will never hear from.Like some of you, I spent some of my childhood in a single parent family. And I can tell you, you are seeing just as much physical leadership in the heart of British households as you will in any wealthy cooperation.Don’t tell working women who are left to juggle the bread winning and the childcare about logistics and procurement.Don’t tell these people about hard work. They are often working two or three jobs whilst keeping businesses going. We often talk about entrepreneurship as if it is always a choice but these people don’t do it because they’d like to be on the front of Forbes magazine or Fortune. They do it because they can’t.They can’t find employers who understand flexible hours or the unique problem faced by juggling priorities with debts, they just do it themselves.They reinvent the world one day at a time, and they do it quietly.Financially fragile, women with multiple caring responsibilities, women whose partners careers have been the priority.It was once said necessity was the mother of invention but it’s actually the other way around.These entrepreneurial mothers are the invention of necessity, and I want them to thrive.These people are resilient, resourceful and remarkable leaders and I wish our great business schools would spend more time studying them.You don’t hear much about them because getting on social media or joining a political organisation when you are working 18 hours a day is tough.You don’t have time to listen, or talk, or network, or come to events like this.You only have time do what needs to be done. Remember Ginger Rogers saying that she did everything Fred Astaire did but she did it backwards and in heels?Well these days it is more likely to be with no back up and in debt.And for too long women have endured being at best patronised and at worst being casually insulted by a generation of men that elevated confidence to entitlement.And so, as we call for change today and we focus on the barriers on attitudes to change and more women taking decisions in venture capital, we should also think about the conditions for success.Did you know that the fastest growing group of entrepreneurs in the US are black women, running about 2.4 million businesses across the country?And guess which group has the least access to capital?Yeah, you guessed it.And there are roughly the same percentage of women, working in, and taking decisions in venture capital in the UK as in the US – very few.So what’s the difference, why in some parts of the United States are women entrepreneurs thriving, despite this?Access to capital is one part, but its more so about skills, about confidence, and it’s about networks and support.So when you listen to the amazing speakers you are going to hear today, from Mumsnet founder Justine Roberts, who built her business around her personal view that she recognised others had too.And Mary Portas who credits her success to collaborative colleagues and networks.And when you hear what has made a difference, such as Innovate UK’s Women in Innovation campaign, which resulted in a 70% increase in registrations for funding in female applicants.Let us think how we can take that and translate that for the women who aren’t here today.I am very pleased that the Treasury has announced that Alison Rose, Chief Executive Officer for RBS Private Banking, will be leading an independent review into the particular barriers faced by women entrepreneurs, and the keys to their success.We need to do more of this and learn from other nations liked the United States.So thank you Jo and The Telegraph for providing a platform, for us to do this.And thank you for being here today.Not just for yourselves, and your own businesses and your own ambitions but thousands of other women too.Thank you.Have a great day.last_img read more

US police weigh officer discipline after rally, Capitol riot

first_imgPolice departments across the country are reviewing the behavior of dozens of officers who were in Washington on the day of the deadly riot at the U.S. Capitol. An Associated Press review finds at least 31 officers are being scrutinized or face criminal charges tied to the Jan. 6 events in the nation’s capital. Most haven’t been publicly identified and only a few have been charged. Experts say it’s up to police chiefs to strike a balance between maintaining their officers’ First Amendment rights and dealing with community mistrust of those officers who were on the scene in Washington.last_img read more

Biden says ‘erratic’ Trump shouldn’t get intel briefings

first_imgWASHINGTON (AP) — President Joe Biden says Donald Trump’s “erratic behavior” should prevent him from receiving classified intelligence briefings, a courtesy that historically has been granted to outgoing presidents. Asked in an interview with CBS News on Friday what he feared if Trump continued to receive the briefings, Biden said he did not want to “speculate out loud.” But he made clear he did not want Trump to continue to receive the briefings. Whether to give a past president intelligence briefings is solely the current officeholder’s prerogative. Trump’s second impeachment trial is set to begin next week.last_img read more

Moody’s downgrades Contura Energy, says outlook remains negative

first_img FacebookTwitterLinkedInEmailPrint分享S&P Global Market Intelligence ($):Moody’s downgraded Contura Energy Inc.’s corporate family rating to B3 from B2 and revised its outlook on the company to negative from stable, saying it expects Contura will experience significant margin compression in 2020 as a result of decreased metallurgical coal prices and higher cash burn.The rating agency also lowered the NYSE-listed coal miner’s senior secured term loan rating to Caa1 from B3, and its speculative grade liquidity rating to SGL-3 from SGL-2, in a Feb. 27 note.Moody’s estimated Contura Energy’s “management-defined” EBITDA would fall to a range of about $125 million to $175 million in 2020, compared to $335 million in 2018 and $264 million for the first nine months of 2019.Contura Energy’s thermal coal platform will likely generate modest losses in 2020 as the company also faces potential headwinds due to variations in metallurgical coal prices, while the negative outlook also reflects expectations for cash consumption in 2020, Moody’s said.“An increasing portion of the global investment community is reducing or eliminating exposure to the coal industry with greater emphasis on moving away from thermal coal,” Moody’s said.Moody’s said it expects 2020 to be very challenging for the coal industry due to lower domestic demand for thermal coal and substantive reductions in export prices, amid increasing difficulty in accessing capital early in the year as investors increase focus on the industry’s environmental, social and governance profile.[Robert Vergara]More ($): Moody’s revises outlook on Contura Energy to negative from stable Moody’s downgrades Contura Energy, says outlook remains negativelast_img read more
