Metadata for the HiWASE instrumentation deployed on the OWS Polarfront between September 2006 and December 2009
No full textBetween 1978 and 2009 the Norwegian weather ship Polarfront made continuous meteorological and surface wave measurements at Station M (66oN 2oE). In September 2006, as part of the UK-SOLAS HiWASE project (Brooks et al., 2009) the ship’s existing systems were complemented by the AutoFlux system (Yelland et al., 2009) to measure the transfers of momentum, heat and CO2 between the atmosphere and the ocean. Similarly, the ship's existing ship-borne wave recorder (SBWR) was supplemented by installing a commercial directional wave radar "WAVEX" made by the Norwegian firm MIROS.This report describes the metadata for the HiWASE instrumentation deployed on the OWS Polarfront between September 2006 and December 2009. Sensor serial numbers, dates of sensor changes and problems with sensors are contained in the associated tables

Characterizing the time-perspective of nations with search engine query data
No full textVast quantities of data on human behavior are being created by our everyday internet usage. Building upon a recent study by Preis, Moat, Stanley, and Bishop (2012), we used search engine query data to construct measures of the time-perspective of nations, and tested these measures against per-capita gross domestic product (GDP). The results indicate that nations with higher per-capita GDP are more focused on the future and less on the past, and that when these nations do focus on the past, it is more likely to be the distant past. These results demonstrate the viability of using nation-level data to build psychological constructs

Morphological properties of moat-drift systems around the world
No full textTo facilitate a comprehensive study of moat-drift systems, we analysed moats from different locations around the world. We measured the following morphological parameters: width, relief, slope angle, drift angle. As there is no moat without an associated drift, we see them as one system that we refer to as a moat-drift system. The moat trough is the deepest point in the moat and the drift crest the shallowest point of the contourite drift. The moat width is defined as the horizontal distance between the drift crest and the slope. The relief is defined as the vertical distance between moat trough and drift crest. The slope angle and the drift angle are the average gradient in both flanks of the moat: 1) between the moat trough and the slope and 2) between the moat trough and the drift crest. The previously published moats were measured from the seismic or sub-bottom profiler cross sections that were published either in a journal or on the GeoMapApp (www.geomapapp.org). In the cases in where multibeam data are available, we measured the parameters from the bathymetric map
Chiral spin liquid state of strongly interacting bosons with a moat dispersion: a Monte Carlo simulation
No full textWe consider a system of strongly interacting bosons in two dimensions with
moat band dispersion which supports an infinitely degenerate energy minimum
along a closed contour in the Brillouin zone. The system has been theoretically
predicted to stabilize a chiral spin liquid (CSL) ground state. In the
thermodynamic limit and vanishing densities, , chemical
potential, , of the uniform CSL state was shown to scale with as
. Here we perform a Monte Carlo simulation to find the
parametric window for particle density, ,
where is the linear size of the moat (the radius for a circular moat),
for which the scaling in the equation of state of the
homogeneous CSL is preserved. We variationally show that the uniform CSL state
is favorable in an interval beyond the obtained scale and present a schematic
phase diagram for the system. Our results offer some density estimates for
observing the low-density behavior of CSL in time-of-flight experiments with a
recently Floquet-engineered moat band system of ultracold atoms in Phys. Rev.
Lett. 128, 213401 (2022), and for the recent experiments on emergent excitonic

Domestic abuse prevention after Raoul Moat
No full textThis article charts the development of domestic abuse policy between May 2010 and June 2011, a period in which: the UK witnessed a high profile domestic abuse case - that of Raoul Moat - pass almost without recognition as such; whilst the dismantling of much of the infrastructure used to prevent domestic abuse outside the criminal justice system commenced, in anticipation of cost-cutting reform designated necessary to the advent of the 'Big Society'. The article uses both the research literature on domestic abuse and the case of Raoul Moat to argue that preventative work in this field needs to keep issues of gender - especially masculinity - in the political frame. This focus on masculinity should not, however, be reduced merely to attitudes accepting of violence or macho values, but should, the article argues, also keep the relationships between violence, emotional dependency, heterosexual propriety, and life crises in view. The article queries whether the Coalition government's focus on 'payback', 'discipline' in schools and the 'sexualization of children' is likely to help more than hinder in this regard, and points to the real risks entailed in economic restructuring that increases the proportion of women and children vulnerable to repeat victimization. © The Author(s) 2012
Future exploitation of in-situ wave measurements at Station Mike
No full textAs part of a UK-SOLAS (Surface Ocean-Lower Atmosphere Study) project the National Oceanography Centre (NOCS) has instrumented the Norwegian weather ship Polarfront with the directional wave radar “WAVEX”. This system complements the Polarfront’s existing ship borne wave recorder which was installed by the Norwegian Meteorological Institute in 1978. The Polarfront and its predecessors have occupied Station Mike (66°N, 2°E) all year round for nearly 60 years. NOCS also equipped the ship with digital cameras and the autonomous air-sea flux system “AutoFlux”. The NOCS systems were installed in September 2006 and will operate continuously for at least 3 years. Project information and real-time data from the ship can be found via http://www.noc.soton.ac.uk/ooc/CRUISES/HiWAS/index.php . The sea-state dataset being obtained on the Polarfront is unparalleled in that the SBWR provides reliable wave height data but no directional information, whereas the wave radar provides excellent directional wave spectra but infers wave heights indirectly. It is believed that, until now, the two systems have never been deployed together for more than brief periods. On Polarfront the two systems provide very comprehensive information on sea state, in a region of the world’s oceans which experience a wide range of conditions (e.g. 3-hourly significant wave height of 15.5 m in November 2001). The main research aim of the project is the parameterisation of the air-sea fluxes, including wind stress, in terms of wind speed, sea state etc. However, the wave data set being collected has potential uses which fall outside the project aims and we would welcome proposals for collaboration from members of the remote sensing and modelling communities. Here we describe initial results which show that the two wave systems agree reasonably well for wave period, but that significant wave heights from the WAVEX are overestimated in the presence of swell
Synthesis and evaluation of historical meridional heat transport from midlatitudes towards the Arctic
No full textMeridional Energy Transport (MET), both in the atmosphere (AMET) and ocean (OMET), has significant impact on the climate in the Arctic. In this study, we quantify AMET and OMET at subpolar latitudes from six reanalyses datasets. We investigate the differences between the datasets and we check the coherence between MET and the Arctic climate variability from annual to interannual scales. The results indicate that, although the mean transport in all datasets agree well, the spatial distribution and temporal variations of AMET and OMET differ substantially among the reanalysis datasets. For the ocean, only after 2010 the low-frequency signals for all reanalyses products agree well. A further comparison with observed heat transports at 26.5° N and the subpolar Atlantic, and a high-resolution ocean model hindcast confirm that the OMET estimated from reanalyses are consistent with independent observations. For the atmosphere, the variations among reanalyses datasets are large. This can be attributed to differences in temperature transport. A further analysis of linkages between the Arctic climate variability and AMET shows that atmospheric reanalyses differ substantially from each other. Among all the chosen atmospheric products, ERA-Interim results are most consistent with results obtained with coupled climate models. For the ocean, ORAS4 and SODA3 agree well on the relation between OMET and sea ice concentration (SIC), while GLORYS2V3 deviates from those data sets. Our study suggests, since the reanalyses products are not designed for the quantification of energy transport, the AMET and OMET estimated from reanalyses should be used with great care, especially when studying variability and interactions between the Arctic and midlatitudes beyond annual time scales
