Cinca River Field Survey: sediment sampling and tree measurement
<p>A field survey was performed on 26-28 November 2018 by Melissa Latella, Matteo B. Bertagni, Paolo Vezza and Carlo Camporeale (Envirofluidgroup, Department of Environmental, Land and Infrastructure Engineering, Polytechnic of Turin, Italy). The survey was carried out over the riparian area of the Cinca River, in a river segment located between the towns of Ballobar and Zaidín (Spain).</p> <p>Sediment samples were collected through the Wolman Pebble Count method. Pictures of the samples constitute the input for the MATLAB-based image-processing tool BaseGrain. BaseGrain allows to extrapolate the intermediate diameter of a set of samples. The output diameters can be processed in order to obtain the grain size distribution, the d50 and d90, and the Manning coefficient.</p> <p>Also vegetation features were measured during the survey. Tree diameter and height were collected in order to regress allometric curves, whereas the number of trees in areas of known extension allows to determine the spatial tree density.</p>
Data and Code from: Using cameras for precise measurement of two-dimensional plant features: CASS
<p>Computer vision explanation: The code (https://github.com/amy-tabb/CASS, referred to as CASS) takes an image of an object on top of an aruco calibration pattern, calibrates the camera using the detected aruco information as well as EXIF tag information, and undistorts and computes the homography from the current location of the aruco calibration pattern in the image to its location in physical space. Then the image is warped to match the coordinate system of the aruco coordinate system, scaled by a user-selected parameter.</p> <p>This dataset provides examples of properly-formatted input images and accompanying text files, as well as a successful run where the option of writing intermediate results has been selected. Details about how to format the directories is found in the README of https://github.com/amy-tabb/CASS.</p> <ul> <li><code>iphone6</code>. is a directory of input files using the camera of a iPhone 6 cellular phone.</li> <li><code>iphone6_results</code>. is the directory of results created from running CASS on <code>iphone6</code>.</li> <li><code>CanonEOS60D</code>. is a directory of input files using a DSLR camera from Canon, model name EOS 60D.</li> <li><code>CanonEOS60D_results.</code> is the directory of results created from running CASS on <code>CanonEOS60D</code>.</li> </ul> <p>See the <code>Write directory format</code> section of CASS's README for details of all of the files; briefly for this example, <code>warped_ORIGINALFILENAME.jpg</code> is the original image, transformed such that 10 pixels corresponds to 1 millimeter on the two dimensional plane of the calibration pattern.</p> <p>https://github.com/amy-tabb/CASS provides code in C++ for processing on this dataset, as well as as Docker image.</p> <p> </p>

Time series measurements of group-specific picophytoplankton primary production
<p>14C-based primary production by flow cytometrically determined pico plankton (Prochlorococcus, Synechococcus, and photosynthetic picoeukaryotes) were measured at six discrete depths (5, 25, 45, 75, 100, and 125 m) at Station ALOHA. Seawater samples from each depth were subsampled into triplicate 30-mL polycarbonate centrifuge tubes from a pre-dawn cast, inoculated under subdued light with 70 µL of NaH14CO3-, then incubated over the full photoperiod (~12-14 hours). At the end of the incubation period (after sundown), 5 mL of each radiolabeled sample was preserved in cryotubes containing 30 µL of 16% (final concentration 0.24% w/v) microscopy-grade paraformaldehyde, flash-frozen in liquid nitrogen, and stored at -80°C for subsequent flow cytometric sorting. Group-specific rates of 14C-assimilation by Prochlorococcus, Synechococcus, and PPE were determined by measuring the amount of 14C assimilated into populations sorted using a BD Influx sorting flow cytometer. </p>
Time-series measurements of size fractionated primary production (>3 micron) in the subtropical North Pacific Ocean
<p>Filter size-fractionated (>3 μm) particulate 14C-based rates of primary production were measured at six discrete depths (5, 25, 45, 75, 100, and 125 m) throughout the euphotic zone. Seawater samples from each depth were subsampled into triplicate 30-mL polycarbonate centrifuge tubes from a pre-dawn cast, inoculated with 70 µL of NaH14CO3-, then incubated over the full photoperiod (~12-14 hours) on a floating in situ array at the corresponding depths where the water was collected. At the end of the incubation period (after sundown), 25 mL of each sample was vacuum-filtered first onto a 25-mm diameter 3-μm pore size polycarbonate membrane.</p>
Time-series measurements of size fractionated primary production (14C-assimilation) in the subtropical North Pacific Ocean
<p>Filter size-fractionated (>0.2-3 μm) particulate 14C-based rates of primary production were measured at six discrete depths (5, 25, 45, 75, 100, and 125 m) throughout the euphotic zone. Seawater samples from each depth were subsampled into triplicate 30-mL polycarbonate centrifuge tubes from a pre-dawn cast, inoculated with 70 µL of NaH14CO3-, then incubated over the full photoperiod (~12-14 hours) on a floating in situ array at the corresponding depths where the water was collected. At the end of the incubation period (after sundown), 25 mL of each sample was vacuum-filtered first onto a 25-mm diameter 3-μm pore size polycarbonate membrane, then the filtrate was vacuum-filtered onto a 25-mm diameter 0.2-μm pore size polycarbonate membrane filter. The rates reported here are for the >0.2-3 μm size fraction.</p>
Time series measurements of leucine incorporation as a measure of bacterial production in the subtropical North Pacific Ocean
<p>Samples were collected at or in the vicinity of Station ALOHA on 24 different cruises. On each cruise, rates of 3H-Leu incorporation into protein were measured. Seawater samples for measurements of production were collected from pre-dawn vertical hydrocasts at 6 discrete depths (5, 25, 45, 75, 100, 125 m) using polyvinyl chloride sampling bottles affixed to a rosette sampler. Polyethylene amber bottles (125 ml capacity) were subsampled from the CTD rosette bottles, and duplicate acid-cleaned 12 ml polycarbonate centrifuge tubes were filled from each depth. Each polycarbonate tube was inoculated with 20 nmol L-1 (final concentration) 3,4,5-3H-leucine. An additional 1.5 ml per depth was subsampled into 2 ml microcentrifuge tubes containing 100 µl of 100% (w/v) ice-cold trichloroacetic acid (TCA) to serve as a killed blank. The polycarbonate sample tubes were capped and incubated in situ over the photoperiod to measure rates of 3H-Leu incorporation in both dark (through use of black cloth bags) and light on a free-drifting array. At the end of the photoperiod, triplicate 1.5 ml subsamples were removed from each tube and added to 2 ml microcentrifuge tubes containing 100 µl of 100% ice-cold TCA; these tubes were stored frozen until analysis. Samples were processed following a modified method of the microcentrifuge method. </p>
Time series measurements of 14C-based primary production (>0.2 um) in the subtropical North Pacific Ocean
<p>Over a 3-year period (April 2010-April 2013), we measured primary production from vertical profiles at near-monthly time scales in the subtropical North Pacific Ocean. Production measurements were based on <sup>14</sup>C-assimilation into >0.2 um plankton biomass. Seawater for the productivity measurements was collected from predawn CTD hydrocasts into acid-cleaned 500-ml polycarbonate bottles. A total of four replicate 500 ml bottles were subsampled per depth and each bottle was spiked with ~1.85 MBq <sup>14</sup>C-bicarbonate. One hundred milliliters from one replicate per depth was immediately vacuum filtered through a polycarbonate filter as a time zero blank. These filters were placed in 20 ml glass scintillation vials and stored at -20oC until shore-based laboratory processing. The remaining three bottles were hung on a free-drifting array, deployed before dawn, and incubated at their initial collection depths throughout the photoperiod (typically 11-13 hours). After sunset the array was recovered, and 100 ml subsamples of all bottles were filtered under gentle vacuum onto 0.2 um polycarbonate filters that were then placed in scintillation vials and frozen. The total radioactivity added to each sample bottle was determined by subsampling 250 µl aliquots into scintillation vials containing 500 µl of β-phenylethylamine. At the shore-based laboratory, filters were acidified, passively vented, and the resulting radioactivity was determined using liquid scintillation counting.</p>
Time series measurements of nitrogen fixation in the subtropical North Pacific
<p>Rates of N<sub>2</sub> fixation were measured using the <sup>15</sup>N<sub>2</sub> isotopic tracer technique. Sampling occurred during near-monthly Hawaii Ocean Time-series cruises. Whole seawater samples from six discrete depths (5, 25, 45, 75, 100, and 125 m) were subsampled into acid-washed 4.3 L polycarbonate bottles. Between June 2005 and May 2012, 3 mL of <sup>15</sup>N<sub>2</sub> gas was injected into each bottle. Beginning in August 2012, the <sup>15</sup>N<sub>2</sub> gas was first dissolved into seawater and 100 mL of the resulting <sup>15</sup>N<sub>2</sub>-enriched water was added to 4.3 L polycarbonate sampling bottles. The resulting atom % enrichment of stocks of <sup>15</sup>N<sub>2</sub>-enriched seawater was measured using a membrane inlet mass spectrometer. Incubation bottles amended with the <sup>15</sup>N<sub>2</sub> tracer were attached to a free-drifting array and incubated at the discrete depths from which samples had been collected. The array was deployed before dawn and samples were incubated at in situ light and temperature for 24 h. After recovery of the array, the entire volume from each bottle was filtered onto a pre-combusted glass microfiber filter (Whatman 25 mm GF/F) and filters were placed onto pre-combusted pieces of foil in Petri dishes and stored frozen at -20°C. Filters were dried for 24 h at 60°C, pelleted, and the total mass of N and its isotopic signature on each filter were analyzed on an elemental analyzer-isotope ratio mass spectrometer (Carlo-Erba EA NC2500 coupled with ThermoFinnigan Delta S). </p>
Strong-motion seismogeodesy by deeply coupling GNSS receivers and inertial measurement units
<p>Understanding the origin and mechanism of destructive earthquakes is predicated on the faithful recordings of their induced ground displacements near the clearly deformed epicentral regions. Global Navigation Satellite System (GNSS) receivers, such as the GPS sort, have been recognized as the best, if not the only reliable, tool to measure such large displacements. This is achieved within the GNSS receivers by continuously tracking the satellite carrier-phase signals. However, GNSS receivers are likely to lose their fidelity in recording the complete and accurate displacement waveforms in case of fierce ground motions, since their carrier-phase tracking becomes instable when strained by such persistent and high dynamic stress. We hence developed an advanced GNSS receiver architecture where the dynamic stress suffered by the carrier-phase tracking components is compensated for by an embedded inertial measurement unit consisting of one accelerometer and one gyroscope. In this case, the carrier-phase signals can be tracked steadily by GNSS receivers, and the displacement accuracy can be improved from sub-centimeter to millimeter level by about 70% when the ground accelerations reach twice the gravitational acceleration. We believe that this advanced GNSS receiver will be an excellent strong-motion seismometer recording displacements directly at a few millimeter accuracy without missing any earthquake signals, even in case of fierce ground motions.</p>

Measurement and modeling of the radio frequency sheath impedance in a large magnetized plasma
<p>The accompanying files contain digital data for figures in the article "Measurement and modeling of the radio frequency sheath impedance in a large magnetized plasma" by J. R. Myra, C. Lau, B. Van Compernolle, S. Vincena and J. Wright, submitted to the journal Physics of Plasmas.</p> <p><strong>Abstract</strong><br> The DC and RF properties of radio frequency (RF) driven sheaths were studied in the Large Plasma Device (LAPD) at the University of California, Los Angeles. The experiments diagnosed RF sheaths on field lines connected to a grounded plate at one end and an ion cyclotron range of frequencies (ICRF) antenna at the other end. The experimental setup permitted measurement of the RF sheath impedance at the plate as a function of DC sheath voltage, with the latter controlled by varying the RF current applied to the antenna. The DC current-voltage characteristics of these sheaths and the RF sheath impedance measurements were compared with modeling. Hot electrons, present in the LAPD plasma, were inferred to contribute significantly to both the DC and RF currents and hence the RF impedance. It was postulated that at very low power hot electrons could not access the region of the plasma subject to RF waves, resulting in an increased RF impedance. Within some experimental limitations and significant assumptions, an RF sheath impedance model was verified by the experimental data.</p>
Measures to mitigate the spread of COVID-19 in Switzerland
<p>Since February 25, 2020 Switzerland has been affected by COVID-19. Modelling predictions show that this pandemic will not stop on its own and that stringent migitation strategies are needed. Switzerland has implemented a series of measures both at cantonal and federal level. On March 16, 2020 the Federal Council of Switzerland declared “extraordinary situation” and introduced a series of stringent measures. This includes the closure of schools, restaurants, bars, businesses with close contact (e.g. hair dressers), entertainment or leisure facilities. Incoming cross-border mobility from specific countries is also restricted to Swiss citizens, residency holders or work commuters. As of March 20, 2020 mass gatherings of more than five people are also banned. Already in early March various cantons had started to ban events of various sizes and have restricted or banned access to short- and long-term care facilites and day care centers. </p> <p>The aim of this project is to collect and categorize these control measures implemented and provide a continously updated data set, which can be used for modelling or visualization purposes. Please use the newest version available. </p> <p>We collect the date/duration and level of the most important measures taken in response to COVID-19 from official cantonal and federal press releases. A description of the measures, the levels as well as the newest version of data dataset can be found <a href="https://github.com/baffelli/covid-2019-measures">here</a>. </p>
