    Long-term dynamics across a volcanic rift: 21 years of microgravity and GPS observations on the southern flank of Mt. Etna volcano (2018)
    ELSEVIER SCIENCE BV
    Details
    Publication Date: 2019-12-05
    Description: In this paper, an integrated analysis of microgravity and ground deformation measurements at Mt. Etna is performed over a 21-years time span (1994-2014), a period encompassing several flank and summit eruptions. Data were collected along a common gravity and ground deformation network located on the volcano's southern flank to monitor the dynamics of the main volcanic and tectonic processes. Gravity variations have first been corrected for the free-air effect using the vertical deformation and the experimental vertical gravity gradients measured at each station. The free-air corrected gravity changes were then reduced for seasonal fluctuations, mainly imputable to water-table fluctuations, and for high frequency variations (noise). This long-term dataset constitutes a unique opportunity to examine the behavior of Mt. Etna in a period in which the volcano exhibited different styles of activity characterized by recharging, flank eruptions and fountaining episodes at summit craters. The joint analysis highlights common periods in which gravity and deformation underwent contemporaneous changes occurring mainly in the central and eastern stations of the profile. Specifically, it was possible to distinguish three different sectors, showing significant deformation and gravity patterns: a western sector, lying west of the South Rift, a central one between the South Rift and the 1989 fracture zone, and an eastern one lying east of the 1989 fracture system. The data shows that the deflation dynamics accompanying the eruptive phases mainly affect the western portion of the profile, gradually disappearing toward East, where the more constant sliding dynamics dominates. This pattern defines a transition zone corresponding to the sector comprised between the South Rift and the 1989 fracture. Furthermore, it was also possible to detect at least three main magma charging phases in 1996,2000 and 2011 which preceded and accompanied the onset of intense flank eruptions and lava fountaining activity at the summit craters.

    Description: Marine and terrestrial sediments of the Valanginian age display a distinct positive d13C excursion, which has recently been interpreted as the expression of an oceanic anoxic episode (OAE) of global importance. Here we evaluate the extent of anaerobic conditions in marine bottom waters and explore the mechanisms involved in changing carbon storage on a global scale during this time interval. We asses redox-sensitive trace-element distributions (RSTE; uranium, vanadium, cobalt, arsenic and molybdenum) and the quality and quantity of preserved organic matter (OM) in representative sections along a shelf-basin transect in the western Tethys, in the Polish Basin and on Shatsky Rise. OM-rich layers corresponding in time to the d13C shift are generally rare in the Tethyan sections and if present, the layers are not thicker than several centimetres and total organic carbon (TOC) contents do not surpass 1.68 wt.%. Palynological observations and geochemical properties of the preserved OM suggest a mixed marine and terrestrial origin and deposition in an oxic environment. In the Polish Basin, OM-rich layers show evidence for an important continental component. RSTE exhibit no major enrichments during the d13C excursion in all studied Tethyan sections. RSTE enrichments are, however, observed in the pre-d13C excursion OM-rich "Barrande" levels of the Vocontian Trough. In addition, all Tethyan sections record higher Mn contents during the d13C shift, indicating rather well-oxygenated bottom waters in the western Tethys and the presence of anoxic basins elsewhere, such as the restricted basins of the North Atlantic and Weddell Sea. We propose that the Valanginian d13C shift is the consequence of a combination of increased OM storage in marginal seas and on continents (as a sink of 12C-enriched organic carbon), coupled with the demise of shallow-water carbonate platforms (diminishing the storage capacity of 13C-enriched carbonate carbon). As such the Valanginian provides a more faithful natural analogue to present-day environmental change than most other Mesozoic OAEs, which are characterized by the development of ocean-wide dysaerobic to anaerobic conditions.

    Environmental factors affecting the standing crop of foraminifera in sublittoral and psammolittoral communities of a Long Island salt marsh (1972)

    Notes: Abstract Representative samples from the epiphytic and psammolittoral communities were made during the summer of 1968 in North Sea Harbor, Southampton, Long Island, USA. In the epiphytic communities, the foraminifera were very patchy; 2.6% of the total samples accounted for 56.4% of the total foraminifera collected. The standing crop and species composition of the foraminifera changed throughout the summer. Two seasonal peaks were observed in the epiphytes. In early summer Protelphidium tisburyensis was the dominant form. In late July and August Elphidium incertum was dominant. Taken as a whole over the entire summer, the following species comprised the epiphytic foraminiferan community: Elphidium incertum (46.63%); Protelphidium tisburyensis (25.64%); Ammotium salsum (9.88%); Elphidium clavatum (6.74%); E. translucens (3.47%); Ammonia beccarii (2.83%); Ammobaculites dilatatus (2.08%); Trochammina inflata (1.8%); Elphidium advenum (〈 1%); E. galvestonense (〈 1%); E. gunteri (〈 1%); Quinqueloculina lata (〈 1%); Q. seminulum (〈 1%) and Trochammina macrescens (〈 1%). Although fewer species were found, many more foraminifera live in the benthos than in the epiphytic community. Taken as a whole, over the entire summer, the following species comprised the foraminifera in the psammolittoral community: Trochammina inflata (49.6%); Elphidium incertum (31.8%); Ammotium salsum (10.9%); Quinqueloculina seminulum (4.2%); Elphidium sp. (1.5); Protelphidium tisburyensis (0.9%); Ammonia beccarii (0.7%); Elphidium clavatum (〈 0.1%); and E. translucens (〈 0.1%). Three species, Ammotium salsum, Elphidium incertum and Trochammina inflata bloomed successively in the psammolittoral community. The distribution of the latter two species was correlated with the vertical and horizontal changes of grain size; Elphidium incertum distribution clustered around a median grain size of 0.1 mm, whereas Trochammina inflata clustered around a median grain size of 0.46 mm. The sediments were sampled both at high and low tide. No evidence was obtained to suggest migration of foraminifera through the sediments as a function of tidal cycle. Horizontal distribution of the foraminifera in the marsh was correlated with the flow patterns of very small rivulets in the study area. With respect to many species of foraminifera, the overlying epiphytic communities are not continuous with the psammolittoral communities below them in the water column. Protelphidium tisburyensis was an early summer dominant epiphyte, but was rare in the psammolittoral communities. Trochammina inflata, on the other hand, was dominant in the coarser, deeper sediments and was rare in the epiphytic community. Elphidium incertum is presumably a generalist species. It formed half the foraminiferan population throughout the water column. Ammotium salsum was also abundant in both communities.

    Notes: Abstract. The problem of presenting database query results has not been investigated sufficiently. This work proposes an approach to identify effective presentations for the results of database queries. This will be done by considering different kinds of information, such as user goals, the characteristics of the data to be presented, and the relationships among them. Our approach is based on the definition of composition operations which, on the basis of elementary presentation types, allow us to obtain designs of complex final presentations. Some effectiveness criteria are considered in order to identify those presentations which best match the user's goals and cognitive abilities. We consider multimedia environments at both the data and presentation level.

    Notes: Abstract Objective: There is now good evidence that inhaled salmeterol is an effective agent in chronic obstructive pulmonary disease (COPD),but, at the present time, data on the effects of bambuterol, which is an oral tarbutaline pro-drug, in patients with COPD are scarce. Moreover, no comparative study between bambuterol and salmeterol in patients with chronic obstructive airway disorders has been published. The objective of this research was, consequently, to compare the efficacy and safety of 20 mg oral bambuterol and 50 μg inhaled salmeterol in patients with partially reversible COPD. Methods: The speed and length of bronchodilation with 20 mg bambuterol and 50 μg inhaled salmeterol were compared in 16 patients with partially reversible COPD. The investigation and designed as a double-blind, double-dummy, cross-over, placebo controlled and randomised study. Lung function (FEV1, FVC) and systemic variables (subjective tremor, heart rate, blood pressure) were monitored prior to the administration of the drug and for 12 h after each agent on 3 non-consecutive days. Results: Inhalation of salmeterol induced a significant (P 〈 0.05) increase of lung function when compared with placebo. In addition, oral bambuterol elicited good bronchodilation, with its maximum slightly later than for salmeterol. The mean (±SE) AUC0–12 hs for all patients were 3.134 1 ± 0.553 for salmeterol and 1963 1 ± 0.573 for bambuterol. Both AUC0–12 h s were significantly greater than for placebo (P 〈 0.05), but there was no significant difference (P = 0.077) between the salmeterol and bambuterol AUC0–12 hs. Bambuterol, but not salmeterol, caused tremor in four patients. Moreover, it induced a higher heart rate when compared with salmeterol at each considered time after the administration of the drug; differences after 9 and 12 h  were statistically significant (P 〈 0.05). Conclusion: Both oral bambuterol and inhaled salmeterol resulted in good bronchodilation in patients with stable COPD. However, bambuterol, but not salmeterol, caused tremor in several subjects and elicited a more pronounced tachycardia.
