The seismic response to Faroe basalts from integrated borehole and wide-angle seismic data

We study the seismic response of layered basalts in the Faroe Islands using borehole data and\ud vertical seismic profiles from the Vestmanna borehole, combined with reflection and wideangle\ud seismic data recorded into arrays of both borehole and land multicomponent receivers.\ud Imaging through the basalt cover in the Faroe-Shetland Basin is a challenge for conventional\ud seismic surveys: scattering caused by the high reflectivity of the basalt as well as intra-basalt\ud multiples and high attenuation from the layered sequence make it difficult to image within\ud and beneath the basalts. This project allows us to correlate ultrasonic-scale velocity and\ud density measurements from the borehole together with ground-truthing from borehole logs\ud and core samples with the seismic-scale velocities and reflection images derived from VSP\ud and surface data. We find a good match of observed travel-times of borehole and wide-angle\ud P-wave data with those predicted from the borehole measurements, suggesting lateral\ud homogeneity over horizontal distances on the kilometre scale, and restricted transverse\ud anisotropy of the layered basalts. A pronounced intra-basalt reflector identified on the\ud multichannel surface seismic can be correlated with lithostratigraphic interpretation of the\ud borehole logs as caused by thick flows near the top of the Lower Basalt formation

Determining the economic costs and benefits of conservation actions: A decision support framework

The need for conservation action to be cost-effective is widely accepted, resulting in increased interest and effort to assess effectiveness. Assessing the financial and economic costs of conservation is equally important for assessing cost-effectiveness, yet their measurement and assessment are repeatedly identified as lacking. The healthcare sector, in contrast, has made substantial progress in identifying and including costs in decision-making. Here, we consider what conservation can learn from this experience. We present a three-step framework for identifying and recording the relevant economic costs and benefits of conservation interventions where the user (1) describes the costing context, (2) determines which types of cost and benefit to include, and (3) obtains values for these costs and benefits alongside metadata necessary for others to interpret the data. This framework is designed to help estimate economic costs but can also be used flexibly to record the direct costs of interventions (i.e., financial costs) and calculate financial and economic benefits. Although recording data on economic costs and benefits is deceptively complex, this framework facilitates improved recording, and indicates how collating this data could enhance the assessment of cost-effectiveness across conservation contexts using a range of decision-making tools. © 2022 The Authors.

Seismic and petrophysical properties of Faroe Islands basalts: the SeiFaBa project

Flood basalt-covered basins exist worldwide along continental margins and are now in focus as targets for future hydrocarbon exploration. It is generally difficult to image through the basalt cover by conventional seismic reflection methods, and this is a major challenge to future petroleum exploration offshore the Faroe Islands. Long-offset profiling has proven very successful (White et al. 2003). Surprisingly, however, it is possible to image through kilometre-thick basalt sequences on some conventional profiles. Details of basalt stratigraphy are revealed on old, reprocessed seismic profiles as well as on recently acquired profiles, even though the imaging may be unsuccessful on nearby profiles (e.g. Boldreel & Andersen 1993). This stresses the need for a better understanding of the acoustic and other physical properties of basalt as well as of the degree of three-dimensional heterogeneity. The SeiFaBa project (Seismic and petrophysical properties of Faroes Basalt, 2002–2005) is funded by the Sindri Group as part of the programmes for licensees within the Faroese offshore area, and addresses these issues with special focus on the subaerially extruded flood basalts of the Faroe Islands (cf. Japsen et al. in press)

Struggling with Adversities of Life: The Role of Forgiveness in Patients Suffering from Fibromyalgia

Objectives: We compared the magnitude and direction of associations between forgiveness and pain, mental and physical health, quality of life, and anger in a sample of fibromyalgia (FMS) patients and healthy controls. In addition, we compared FMS and controls on mean levels of these variables. Methods: 173 FMS patients and 81 controls completed this study. Patients and controls were residents of Germany recruited with the support of the German Fibromyalgia Patient Association and several self-help groups. FMS patients and controls were about 53 years of age, mostly married (70%), Christians (81%), with levels of education ranging from 9 years to 13+. All participants completed assessments of forgiveness, pain, health, quality of life, and anger. Results: Analyses revealed that FMS patients reported higher pain and anger and poorer health and quality of life. FMS patients also reported lower levels of both forgiveness of self and others. Size and direction of associations of forgiveness with pain, health, quality of life, and anger in were not significantly different between healthy individuals and patients with FMS. Discussion: Forgiveness of self and others is beneficially associated with pain, health, quality of life, and anger in FMS patients at levels that are of similar size and direction as in healthy controls. However, FMS patients manifest lower levels of forgiveness of self and others. Therapeutic promotion of forgiveness as a psychosocial coping strategy may help patients with FMS to better manage psychological and physical symptoms, thereby enhancing well-being

Interannual variability in the pathways of the North Atlantic Current over the Mid-Atlantic Ridge and the impact of topography

The definitive version was published in Journal of Physical Oceanography 38 (2008): 104–120, doi:10.1175/2007JPO3686.1.Recent studies have indicated that the North Atlantic Ocean subpolar gyre circulation undergoes significant interannual-to-decadal changes in response to variability in atmospheric forcing. There are also observations, however, suggesting that the southern limb of the subpolar gyre, namely, the eastward-flowing North Atlantic Current (NAC), may be quasi-locked to particular latitudes in the central North Atlantic by fracture zones (gaps) in the Mid-Atlantic Ridge. This could constrain the current’s ability to respond to variability in forcing. In the present study, subsurface float trajectories at 100–1000 m collected during 1997–99 and satellite-derived surface geostrophic velocities from 1992 to 2006 are used to provide an improved description of the detailed pathways of the NAC over the ridge and their relationship to bathymetry. Both the float and satellite observations indicate that in 1997–99, the northern branch of the NAC was split into two branches as it crossed the ridge, one quasi-locked to the Charlie–Gibbs Fracture Zone (CGFZ; 52°–53°N) and the other to the Faraday Fracture Zone (50°–51°N). The longer satellite time series shows, however, that this pattern did not persist outside the float sampling period and that other branching modes persisted for one or more years, including an approximately 12-month time period in 2002–03 when the strongest eastward flow over the ridge was at 49°N. Schott et al. showed how northward excursions of the NAC can temporarily block the westward flow of the Iceland–Scotland Overflow Water through the CGFZ. From the 13-yr time series of surface geostrophic velocity, it is estimated that such blocking may occur on average 6% of the time, although estimates for any given 12-month period range from 0% to 35%.This research was supported by National Science Foundation Grants OCE-9531877 to the Woods Hole Oceanographic Institution (WHOI) and OCE-9906775 to the University of Rhode Island, by the WHOI Summer Student Fellowship Program, and by the Lawrence J.

Anti-pseudomonad Activity of Manuka Honey and Antibiotics in a Specialized ex vivo Model Simulating Cystic Fibrosis Lung Infection

Pseudomonas aeruginosa causes problematic chronic lung infections in those suffering from cystic fibrosis. This is due to its antimicrobial resistance mechanisms and its ability to form robust biofilm communities with increased antimicrobial tolerances. Using novel antimicrobials or repurposing current ones is required in order to overcome these problems. Manuka honey is a natural antimicrobial agent that has been used for many decades in the treatment of chronic surface wounds with great success, particularly those infected with P. aeruginosa. Here we aim to determine whether the antimicrobial activity of manuka honey could potentially be repurposed to inhibit pulmonary P. aeruginosa infections using two ex vivo models. P. aeruginosa isolates (n = 28) from an international panel were tested for their susceptibility to manuka honey and clinically relevant antibiotics (ciprofloxacin, ceftazidime, and tobramycin), alone and in combination, using conventional antimicrobial susceptibility testing (AST). To increase clinical applicability, two ex vivo porcine lung (EVPL) models (using alveolar and bronchiolar tissue) were used to determine the anti-biofilm effects of manuka honey alone and in combination with antibiotics. All P. aeruginosa isolates were susceptible to manuka honey, however, varying incidences of resistance were seen against antibiotics. The combination of sub-inhibitory manuka honey and antibiotics using conventional AST had no effect on activity against the majority of isolates tested. Using the two ex vivo models, 64% (w/v) manuka honey inhibited many of the isolates where abnormally high concentrations of antibiotics could not. Typically, combinations of both manuka honey and antibiotics had increased antimicrobial activity. These results highlight the potential of manuka honey as a future antimicrobial for the treatment of pulmonary P. aeruginosa isolates, clearing potential infection reservoirs within the upper airway
