Full Name* Share via Shortlink Email Address* 212 Columbia Heights (Leslie J. Garfield)After a month of record-breaking sales, a Brooklyn Heights townhouse hit the market asking $18.25 million.The asking price on the 8,250-square-foot home pencils out to $2,212 per square foot. As a comparison, a mansion a couple of blocks away that’s about 3,000 square feet larger recently sold for over $25 million.The six-bedroom home at 212 Columbia Heights listed last week. It appears to be owned by financier Mark Werner and his wife Dawn, according to property records. The couple bought the home in 2012 for $11 million. At the time, it was the priciest sale recorded in the borough since 2003, according to the Brooklyn Eagle.Werner is an adviser to private equity firm Cerberus Capital Management; he previously co-founded Amherst Pierpont Securities and led Bank of America’s global markets team.The townhouse is 25 feet wide, spans five stories, has a private outdoor garden and views of New York Harbor and the Manhattan skyline. The structure originally dates to 1855, though the home was recently gut-renovated. Original flooring, fireplace mantels and plaster moldings have been preserved and restored.212 Columbia Heights is a couple of blocks from 8 Montague Terrace, the 11,600-square-foot townhouse that billionaire Vincent Viola and his wife Theresa sold last month for $25.5 million. The deal made it the highest price ever recorded in the borough. The sale penciled out to $2,202.Both the Columbia Heights and Montague Terrace properties are parallel to the Brooklyn Queens Expressway overlooking the New York Harbor.The listing agent on 212 Columbia, Ravi Kantha of Leslie J. Garfield, said “a turn-key house at this price is a relatively good value.” He pegged the cost of a renovation at $600 per square foot. He added the recent improvements would allow a buyer to move-in immediately. “You’re not spending two to three years of going through the headaches of a gut renovation in New York City.”Kantha, who shares the listing with Matthew Lesser, pointed to sales of 218 Columbia Heights and 192 Columbia Heights, as examples. Both properties sold for about $12 million in 2018, and both are now being renovated.Last week, the average per square foot price of eight Brooklyn townhouses that went into contract asking more than $2 million was $1,078.Contact Erin Hudson Message* Tags Share on FacebookShare on TwitterShare on LinkedinShare via Email Share via Shortlink Read moreVince Viola’s $25.5M mansion sale breaks Brooklyn recordWhat Brooklyn’s record $25.5M sale means for borough’s resi market$6.5M Fort Greene townhouse sale breaks neighborhood record brooklynResidential Real Estate
Petrographic and geochemical studies of peridotites from the South Sandwich forearc region provide new evidence for the evolution of the South Sandwich arc–basin system and for the nature of interactions between arc magma and oceanic lithosphere. Peridotites from the inner trench wall in the north-east corner of the forearc vary from clinopyroxene-bearing harzburgites, through samples transitional between harzburgites and dunites or wehrlites, to dunites. The harzburgites are LREE depleted with low incompatible element abundances and have chromites with intermediate Cr# (ca. 0.40). Modelling shows that they represent the residues from 15–20% melting at oxygen fugacities close to the QFM buffer. The dunites have U-shaped REE patterns, low incompatible element abundances and high Cr# (0.66–0.77). Petrography and geochemistry indicate that the latter are the product of intense interaction between peridotite and melt saturated with olivine under conditions of high oxygen fugacity (QFM + 2). The transitional samples are the product of lesser interaction between peridotite and melt saturated with olivine ± clinopyroxene. The data demonstrate that the harzburgites originated as the residue from melting at a ridge (probably the early East Scotia Sea spreading centre), and were subsequently modified to transitional peridotites and dunites by interaction with South Sandwich arc magmas. The second dredge locality, near the South Sandwich Trench–Fracture Zone intersection, yielded rocks ranging from lherzolite to harzburgite that could similarly have resulted from a two-stage melting and enrichment process, but involving a more fertile mantle residue and a reacting melt that is transitional between MORB and island arc tholeiite. The South Sandwich peridotites have a similar petrogenetic history to those from Conical Seamount in the Mariana forearc in the sense that both involved interaction between arc magma and pre-existing mantle lithosphere of different provenance. However, the precise compositions of the magma and mantle components vary from location to location according to the precise tectonic setting and tectonic history. Overall, therefore, data from the South Sandwich and Izu–Bonin–Mariana systems emphasise the potential significance of peridotite geochemistry in unravelling the complex tectonic histories of forearcs past and present
Geographical information Systems (GIS) provide tools for manipulating and analysing the large thematic datasets associated with Gondwana research. We have used a customised version of Environmental Systems Research Institute’s ArcGIS, version 8.2, as the basis of our ‘Gondwana and Southern Ocean Computer Model’ (GSCM). The additional functionality necessary for paleogeographic work was written in Visual Basic for Applications (VBA), and includes routines for assigning data to the relevant plates (Plate Sieving) and transformation from present to paleo-coordinates (Rotate Data). The sieving function employs a user-supplied plate network, so that the same data can be assigned to different plate systems at different scales. Paleo-coordinate transformations are handled entirely within ArcGIS, preserving the links to data attributes, and thereby permitting spatial analysis with continents in their former configuration. We give a detailed description of these functions, together with some simple examples of the system’s capabilities using data to large igneous provinces.
A particle tracking scheme that uses velocity output from an interannually varying forced run of a global ocean circulation model (Parallel Ocean Climate Model; POCM_4C) allows variability in the transport pathways across the Scotia Sea to South Georgia to be examined for the first time. The time-variant surface fluxes introduce realistic variability into the model velocity fields. This causes large variations in near-surface, mixed-layer transport from the Antarctic Peninsula region to South Georgia, an island in the southwest Atlantic sector of the Southern Ocean. The variability occurs on a variety of timescales with seasonal and longer periods of variability apparent in the 18 year time series of results. A quasi-four year period of variability is evident across the region in the sea surface temperature fields of POCM_4C and appears in the particle tracking results. This period, noted in other Southern Ocean data sets and ascribed to the Antarctic Circumpolar Wave, has been observed in the reproductive success of higher marine predators breeding on the island. The predicted oceanographic variability is likely to be significant for the South Georgia ecosystem by affecting the influx into the region of Antarctic krill (Euphausia superba), the main prey of the higher predators.
Dissolved iodine speciation in surface seawater at a coastal Antarctic site has been studied over a period spanning three austral summers. The sampling site is biologically productive, with a summertime algal bloom accompanying strong seasonal variations in physical and chemical parameters. The results suggest a seasonal cycle in which iodide concentrations increase and iodate concentrations decrease during the summer, though the magnitude of these changes appears to be subject to considerable interannual variability. Iodide concentrations were typically very low, with minimum values of 10 to 20 nM at the beginning and end of the ice-free summer periods and summertime maxima of about 35 nM in 2005/06, 150 nM in 2006/07 and 82 nM in 2007/08. More detailed observations of iodide and iodate concentrations made during summer 2005/06 demonstrated that the accumulation of iodide was strongly correlated with integrated biological primary productivity, with an implied I/C assimilation ratio of 1.6 × 10−4.
Stretching back to Scott’s doomed Terra Nova expedition, the enigmatic polar regions have long been a source of fascination for explorers and scientists alike. Today the polar regions remain a fertile ground for scientific exploration, serving as natural, interdisciplinary laboratories for the pursuit of new knowledge that can refine our understanding of the Earth system. However, the reality of climate change has meant they have taken on a new poignancy, for these frozen worlds are undergoing rapid changes with global impacts.
The proteome can be regarded as a molecular phenotype, as changes in protein expression patterns have a direct effect on organismal physiology and fitness. The analysis of the proteome can therefore be an invaluable tool for our understanding of the mechanisms underlying phenotypic changes in response to environmental change. However, proteomic studies on thermal stress in marine species have mainly focused on heat shock protein expression, and little information is available for other components of the cellular stress response. This is particularly limiting for Antarctic species, which can lack the ability to induce heat shock protein expression in response to experimentally induced heat stress. The present study analysed changes in protein expression patterns in the Antarctic clam Laternula elliptica after exposure to elevated temperatures using two dimensional gel electrophoresis and mass spectrometry. Acute exposure to elevated temperatures had an effect in global protein expression patterns, suggesting that L. elliptica has the capacity to alter protein expression in response to heat stress. Changes in the expression of 14 proteins out of 264 analysed were observed in response to different levels of heat stress. Four of the 14 proteins had database matches and were identified as the cytoskeletal protein tubulin and associated chaperone TCP-1, and the enzymes enolase and aldehyde dehydrogenase, part of the minimal stress proteome and involved in redox regulation.
Investigating the foraging ecology of seabirds is especially challenging given their wide-ranging movements and the practical difficulties of obtaining unbiased information on their feeding behavior. Despite the development of animal-borne tracking devices, several limitations preclude investigations at the scale of a whole community in a given season or year, and, until recently, during the non-breeding period. Here we analyzed δ13C and δ15N in feathers of chicks and adults to investigate inter- and intra-specific variation in the foraging habitat and trophic position of 9 large procellariiform seabirds from 6 southern breeding localities during the breeding and non-breeding periods. Isotopic ratios of each species were generally consistent among different breeding populations, despite the large geographical scale and potential variation in oceanography in surrounding waters. Both spatial and trophic segregation apparently allowed the co-existence of sympatric species in most breeding localities, except at South Georgia, where both δ13C and δ15N in chicks showed high overlap among species, probably resulting from the superabundance of alternative food resources during the summer. Low variance in stable isotope ratios among adults in several species indicated high overlap between individuals in feeding habits and trophic levels (i.e. isotopic specialist populations) during the non-breeding period. By contrast, large isotopic variances and the high within- and between-individual components of the trophic niche width suggested that grey-headed and light-mantled sooty albatrosses are generalists. Based on δ13C, the species that breed in the Southern Ocean can be categorized as residents or subtropical migrants, with the latter including oceanic and neritic subtropical migrants. Albatrosses meet the high energetic challenge of feather synthesis by foraging in different habitats, depending on the length of the non-breeding period. Annual breeders renew their plumage in productive neritic waters in ~4 mo, whereas biennially breeding species moult in less productive oceanic waters over much longer periods (~12 to 16 mo).
The radiation belts and magnetospheres of Jupiter and Saturn show significant intensities of relativistic electrons with energies up to tens of MeV. To date, the question on how the electrons reach such high energies is not fully answered. This is largely due to the lack of high‐quality electron spectra in the MeV energy range that models could be fit to. We reprocess data throughout the Galileo orbiter mission in order to derive Jupiter’s electron spectra up to tens of MeV. In the case of Saturn, the spectra from the Cassini orbiter are readily available and we provide a systematic analysis aiming to study their acceleration mechanisms. Our analysis focuses on the magnetospheres of these planets, at distances of L > 20 and L > 4 for Jupiter and Saturn, respectively, where electron intensities are not yet at radiation belt levels. We find no support that MeV electrons are dominantly accelerated by wave‐particle interactions in the magnetospheres of both planets at these distances. Instead, electron acceleration is consistent with adiabatic transport. While this is a common assumption, confirmation of this fact is important since many studies on sources, losses, and transport of energetic particles rely on it. Adiabatic heating can be driven through various radial transport mechanisms, for example injections driven by the interchange instability or radial diffusion. We cannot distinguish these processes at Saturn with our technique. For Jupiter, we suggest that the dominating acceleration process is radial diffusion because injections are never observed at MeV energies.
Bluenose warehou (Hyperoglyphe antarctica) is a popular commercial fish in Australia and New Zealand, but its biology and ecology are very poorly known in other regions where it is found. We present here the first life history data for this species from the south Atlantic, focusing upon the exclusive economic zone (EEZ) of the United Kingdom Overseas Territory (UKOT) of Tristan da Cunha (TdC). Here, bluenose is known from several seamounts and island margins, typically occurring in waters between 200 and 1,000 m depth and is the target species of trawl and longline fishery operating since 1997. We use a suite of methods to describe important life history parameters, including length-weight and age-length relationships and size at recruitment, as well as examining commercial longline survey data to uncover habitat preferences of bluenose. This work has formed an important part of the United Kingdom government’s Blue Belt Program in TdC. It has underpinned the development of the first stock assessment for this species in the Atlantic, as well as a range of improved conservation measures for some of the more vulnerable species that occur in these areas, including seabirds and cold-water corals.
