Data from: Comparison of carbon and nitrogen accumulation rate between bog and fen phases in a pristine peatland with the fen-bog transition
<p>Long-term carbon and nitrogen dynamics in boreal peatlands are affected by both vegetation production and decomposition processes. Here, we examined the carbon accumulation rate (CAR), nitrogen accumulation rate (NAR) and δ<sup>13</sup>C, δ<sup>15</sup>N of plant residuals in a peat core dated back to ~8500 cal yr BP in a temperate peatland in Northeast China. Impacted by the tephra during 1160 and 789 cal yr BP and climate change, the peatland changed from a fen dominated by vascular plants to a bog dominated by <em>Sphagnum mosses</em>. We used the Clymo model to quantify peat addition rate and decay constant for acrotelm and catotelm layers during both bog and fen phases. Our studied peatland was dominated by <em>Sphagnum fuscum</em> during the bog phase (789 ~ -59 cal yr BP) and lower accumulation rates for the upper sections in the acrotelm layer during this phase, suggesting the dominant role of volcanic eruption in the CAR of the peat core. Both mean CAR and NAR were higher during the bog phase than during the fen phase in our study, consistent with the results of the only one similar study in the literature. Because the input rate of organic matter was considered to be lower during the bog phase, the decomposition process must have been much lower during the bog phase than during the fen phase and potentially controlled CAR and NAR. During the fen phase, CAR was also lower under higher temperature and summer insolation, conditions beneficial for decomposition. δ<sup>15</sup>N of <em>Sphagnum </em>hinted that nitrogen fixation had positive effect on nitrogen accumulation, particular in recent decades. Our study suggested that decomposition is more important for carbon and nitrogen sequestration than production in peatlands in most conditions and if future climate changes or human disturbance increase decomposition rate, carbon sequestration in peatlands will be jeopardized.</p>
Role of breakage, melt and floe size distribution on sea ice summer transition
<p>Marginal ice zones are composed of individual sea ice floes, whose breakage and melt determine its summer behavior. These processes are not well represented by global or regional climate models due to the continuum approximations used for sea ice. Here, we use a Discrete Element Model (DEM) coupled to a slab thermodynamic ocean to investigate how breakage and melt processes impact the decay of summer sea ice. The DEM is calibrated using MODIS satellite imagery and reanalysis data within the Arctic Ocean’s Baffin Bay during June-July 2018. The sensitivity of the sea ice decay is evaluated by varying the solar heating, ice/ocean heat exchange parameter, and a prescribed floe breakage rate. For the parameter regime that best fits observations, the ratios of mass loss of resolved floes (>2 km) due to breakage versus melt is 0.47, and oceanic versus solar melt is 0.46. The rate at which resolved floes lose mass is most sensitive to the breakage rate, as compared to the solar and oceanic melt parameters. The number decay of the largest floes (>21 km) is controlled by breakage, while decay of smaller floes (2 - 21 km) depends strongly on lateral melt. Inferences from this exploration of parameter space may help develop more accurate parameterizations of the floe size distribution evolution in climate models.</p>

Data for the publication "Sensitivity of Banner Cloud Formation to Orography and the Ambient Atmosphere: Transition From Idealized to More Realistic Scenarios"
<p>Data accompanying the paper titled: "Sensitivity of Banner Cloud Formation to Orography and the Ambient Atmosphere: Transition From Idealized to More Realistic Scenarios"</p> <p>This repository contains output statistics for thirty simulations run with the EULAG model in LES mode (Prusa et al., 2008).</p> <p>We use three distinct configurations of the model domain and its orography, ranging from highly idealized to fully realistic. The configuration with realistic orography is referred to as “Matt_Ref” and covers a domain of 12.8 x 9.6 x 7 km. As our intermediate configuration, we use the realistic orography from the Matterhorn summit protruding from a flat plain, referred to as "Matt_Iso". As our highly idealized configuration we consider a Pyramid protruding from a flat plain, referred to as "Pyr". In both configurations the model domain extends 11.6 x 9.2 x 4.5 km. The simulations of all three configurations are performed with an isotropic grid spacing of 25 m.<br> <br> Each zip-file contains the time-averaged fields of six simulations with inflow conditions of a sheared or constant wind profile with 5, 10 and 20 m/s, and neutral stratification up to the height of the mountain summit. For the "Matt_Ref" configuration exists two additional zip-files containing data of a neutral stratification up to 500 meter and 800 meter below the mountain summit. Moreover, for the "Matt_Ref" configuration exists three additional zip-files containing the time-averaged turbulent fields. For more details have a look at the paper.</p>

Transit agencies want open payments but there are challenges
<p>This study explores interest in, and the challenges faced by transit agencies and operators in the adoption of open-loop payment systems. The research team focuses in particular on the ways that agencies view passenger needs in the context of adopting open payments. Challenges with cash payments, an increasingly cashless society, and the expanding offerings of digital payment options have spurred increased interest in open-loop payments among transit operators. Paying for transit with cash can require additional time at boarding, add extra steps for passengers who must pay with exact fare, and result in service inefficiencies. It presents security concerns for drivers, and administrative burdens for agencies. While the full costs of cash handling vary per agency the cost of handling and moving cash may be considerable. Pioneering transit agencies are adopting open payment systems that accept credit cards, debit cards, and smartphone/watch-based transactions. However, there is a huge diversity among transit agencies and as such, agencies face different challenges and to different degrees, when considering the adoption of open payment systems. Challenges can include financial barriers, capacity limitations, technological challenges, the duration of existing contracts, competing needs, and a number of passenger challenges such as lack of credit cards or smartphones. This study uses data collected from California transit agencies in the fall of 2022 that gathered information about agency perceptions of open-loop payments and the challenges with adopting open fare collection systems, and whether assistance programs would benefit transit agencies interested in adopting open-loop payments. Even before the pandemic prompted agencies to consider open and contactless payments, many agencies were exploring this option. Results of the present study indicate that the majority of agencies are considering or have considered implementing open payment systems, but agencies are not fully aware of the assistance available from the California Integrated Travel Program to help in the transition to digital and open payment systems. Key challenges include the cost, as well as the technical needs to implement open payments. Agencies also cited passenger familiarity with technology and ability to have a bank account as potential hurdles. This study sheds light on the challenges facing small to medium transit agencies in the transition of California's transit systems to open-loop payment systems.</p>

TimeFISH: Long-term assessment of reef fish assemblages in a transition zone in the Southwestern Atlantic
<p>The TimeFish database provides the first public time-series dataset on reef fish assemblages in the Southwestern Atlantic (SWA), comprising 15 years of data (2007-2022) based on standardized Underwater Visual Censuses (UVCs). The rocky reefs covered by our dataset are influenced by pronounced seasonal cycles of ocean temperatures with warm tropical waters from the Brazil Current in the summer (~27°C) and colder waters from the La Plata River Plume discharge and upwelling from the South Atlantic Central Water in the winter (~18°C). These oceanographic conditions characterize this area as the southernmost tropical-subtropical climatic transition zone in the Atlantic Ocean. As a result, reef fish assemblages comprise both tropical and subtropical species. All records included in TimeFish were collected using UVCs, a non-destructive method that allows the estimation of fish species richness, abundance, and body size distributions. UVCs were performed through 40 m2 belt transects by scuba diving in nine locations along the southern Brazilian coast (25°S – 29°S). Four of these locations lie within the boundaries of the no-entry Arvoredo Marine Biological Reserve, where fishing and recreational activities are forbidden, and the remaining locations are unprotected from these activities. During each belt transect, a diver swam at a constant depth above and parallel to the reef, identifying fish species, counting the number of individuals, and estimating the total body length (Lt in cm) of all detected individuals. All fish individuals in the water column (up to 2 m above the substratum) and at the bottom were targeted. A total of 202,965 individuals belonging to 163 reef fish species and 53 families were recorded across 1,857 UVCs. All survey campaigns were funded by either public or mixed capital (private-public) sources, including seven grants from the Brazilian federal and Santa Catarina state government. Part of the data have already been used in multiple MSc and Ph.D. theses and scientific articles. TimeFISH represents an important contribution for future studies aiming to examine temporal and spatial variations of reef fish assemblages in transition zones.
