New Last Glacial Maximum ice thickness constraints for the Weddell Sea Embayment, Antarctica

first_imgWe describe new Last Glacial Maximum (LGM) ice thickness constraints for three locations spanning the Weddell Sea Embayment (WSE) of Antarctica. Samples collected from the Shackleton Range, Pensacola Mountains, and the Lassiter Coast constrain the LGM thickness of the Slessor Glacier, Foundation Ice Stream, and grounded ice proximal to the modern Ronne Ice Shelf edge on the Antarctic Peninsula, respectively. Previous attempts to reconstruct LGM-to-present ice thickness changes around the WSE used measurements of long-lived cosmogenic nuclides, primarily Be-10. An absence of post-LGM apparent exposure ages at many sites led to LGM thickness reconstructions that were spatially highly variable and inconsistent with flow line modelling. Estimates for the contribution of the ice sheet occupying the WSE at the LGM to global sea level since deglaciation vary by an order of magnitude, from 1.4 to 14.1m of sea level equivalent. Here we use a short-lived cosmogenic nuclide, in situ-produced C-14, which is less susceptible to inheritance problems than Be-10 and other long-lived nuclides. We use in situ C-14 to evaluate the possibility that sites with no post-LGM exposure ages are biased by cosmogenic nuclide inheritance due to surface preservation by cold-based ice and non-deposition of LGM-aged drift. Our measurements show that the Slessor Glacier was between 310 and up to 655m thicker than present at the LGM. The Foundation Ice Stream was at least 800m thicker, and ice on the Lassiter Coast was at least 385m thicker than present at the LGM. With evidence for LGM thickening at all of our study sites, our in situ C-14 measurements indicate that the long-lived nuclide measurements of previous studies were influenced by cosmogenic nuclide inheritance. Our inferred LGM configuration, which is primarily based on minimum ice thickness constraints and thus does not constrain an upper limit, indicates a relatively modest contribution to sea level rise since the LGM of < 4.6 m, and possibly as little as < 1.5 m.last_img read more

Antarctic Ice Sheet elevation impacts on water isotope records during the Last Interglacial

first_imgChanges of the topography of the Antarctic ice sheet (AIS) can complicate the interpretation of ice core water stable isotope measurements in terms of temperature. Here, we use a set of idealised AIS elevation change scenarios to investigate this for the warm Last Interglacial (LIG). We show that LIG δ 18 O against elevation relationships are not uniform across Antarctica, and that the LIG response to elevation is lower than the preindustrial response. The effect of LIG elevation‐induced sea ice changes on δ 18 O is small, allowing us to isolate the effect of elevation change alone. Our results help to define the effect of AIS changes on the LIG δ 18 O signals, and should be invaluable to those seeking to use AIS ice core measurements for these purposes. Especially, our simulations strengthen the conclusion that ice core measurements from the Talos Dome core exclude the loss of the Wilkes Basin at around 128 ky.last_img read more

Premier Foods to look into attitudes to bread

first_imgPremier Foods is to study why shoppers are binning so much bread.The Hovis manufacturer will team up with Waste & Resources Action Programme (WRAP) to research consumer behaviour and attitudes around buying, storage and usage habits. Findings will be used to develop a targeted approach to help reduce bread waste.Neil Macfarlane, head of insight at Premier Foods, said: “We will gain a better understanding as to why UK consu-mers waste so much ’good food’ and then apply the learnings taken from this research to inform new ways of engaging consumers to encourage a reduction in food waste.”According to a WRAP study, bakery goods accounted for 14.1% of the £10bn cost to UK households of food wastage a total of 782,000 tonnes of wasted bakery products, of which 400,000 tonnes is bread.”Reasons thought to be contributing to consumer bread waste are pack sizes being too large, the product staling or going mouldy as a result of incorrect storage and not being confident around free-zing bread,” said a spokeswoman for WRAP. It follows news that sliced bread is the second most common product binned by Scottish households, according to WRAP Scotland, which said 20% of bread bought by consumers was wasted.l In other news, Hovis has added a new Soft White Farmhouse loaf to its range, which it said is a domed, more traditional version of its Soft White variant. The packaging will feature the Soft White logo as well as a ’new’ flash on-pack. Hovis will be rolling out a £4.5m campaign to support its Soft White range including the new Farmhouse loaf.last_img read more

Indonesia raises another $4b from bonds, in talks with development banks

first_imgIndonesia has raised another Rp 62.62 trillion (US$4.05 billion) from government debt papers (SUN) and is in talks with several development banks to raise another $750 million to finance its widening state budget amid the fight against the coronavirus pandemic.The Finance Ministry’s director for government debt papers, Deni Ridwan, said the government had issued three series of bonds through private placements with commercial and shariah banks on Monday.“Banks are the buyers in the private placements as they look to meet Bank Indonesia’s new requirement of higher reserves in government bonds,” Deni told The Jakarta Post by text message on Tuesday. “COVID-19 emergency funds worth around $200 million to $250 million from the Islamic Development Bank are in the negotiation process,” the finance minister said in a statement on Tuesday.The World Bank and the AIIB were also committed to providing $250 million in funds each for Indonesia’s COVID-19 response, according to the minister. The Asian Development Bank (ADB), meanwhile, has approved $1.5 billion in loans to support Indonesia’s efforts to strengthen public health and the economy.Previously, the country has raised $4.3 billion in dollar-denominated bonds, including the longest-dated 50-year US dollar bond ever issued by an Asian nation, earlier this month. It also sold around Rp 14 trillion of sharia sovereign bonds last week.The central bank has bought Rp 1.72 trillion in a regular auction on Tuesday last week. It has also bought Rp 2.93 trillion on Wednesday in a “greenshoe option”, BI’s head of monetary operations Nanang Hendarsah said according to Reuters.Regulation in Lieu of Law No. 1/2020 issued in March allows the central bank to purchase government bonds directly at auction. Previously, the central bank was only allowed to buy government bonds in the secondary market.Read also: Indonesia to issue Rp 450 trillion in ‘pandemic bonds’ to finance COVID-19 fightFitch Solutions expects Indonesia’s government debt to average 45.3 percent of GDP between 2020 and 2023 compared to 33.1 percent of GDP in the past five years, as the government rolled out tax incentives, including permanent corporate income tax cuts.“As a result, the public debt load is likely to increase significantly during this period, even with offsetting tax policies,” Fitch noted. “It is likely that the ownership structure of government securities will change to some extent with foreign investors’ lowering their holdings considerably and BI seen to expand its balance sheet.”Fitch, however, expressed confidence that, once the worst was over, “Sri Mulyani will ramp up efforts to bring government spending back in line and broaden the revenue base.”Topics : Bank Indonesia (BI) requires that bank buy government bonds after cutting banks’ reserve requirement ratio by 200 basis points (bps) for commercial banks and 50 bps for sharia banks, providing the financial system with Rp 102 trillion in liquidity in a move that is expected to help the government fund the COVID-19 battle, Governor Perry Warjiyo said recently.The government has increased this year’s budget financing by raising Rp 1 quadrillion in loans, a 286 percent jump from the original target of Rp 351.9 billion. It will issue nearly Rp 450 trillion worth of “pandemic bonds” and revise up its bond sales target by Rp 160.2 trillion to Rp 549.6 trillion this year to address the widening budget deficit, which could reach 5.07 percent of gross domestic product (GDP).Read also: Explainer: Indonesia to finance coronavirus battle mostly through debtThe government is also in talks to earn $750 million worth of loans from several development banks, namely the Islamic Development Bank, the World Bank and the Asian Infrastructure Investment Bank (AIIB), Finance Minister Sri Mulyani Indrawati said.last_img read more
