Supplemental tables for a study of the seasonal Impacts of the Physical Environment on Biogeochemical Cycles in Arctic Lakes of the Mackenzie River Delta
<p>submitted abstract</p> <p>We conducted two- and six-year-long deployments of continuous water samplers (OsmoSamplers) and sensors (Temperature, pressure, light level, dissolved oxygen (DO) and conductivity) in nine lakes within the mid- to outer-delta region of the Mackenzie River and documented biogeochemical fluctuations (Mn, Fe, sulfate, and DO), defined physical processes that that drive such fluctuations, and constrained the impact of lake solutes on annual riverine fluxes. Five lakes were in the mid-delta region near Inuvik, NT, two lakes were in the outer delta, and two lakes were on the Arctic coastal plain and were not impacted by the Mackenzie River. In general, temperature minima occurred in September/October, indicative of ice formation, and distinct hydrostatic pressure (water level) anomalies occurred in May/June associated with ice breakup, lasting for days to months and impacting lake levels up to 4.2 m higher than “normal”. Such anomalies coincide with a dramatic change in solute concentrations. Systematic changes in solute concentrations indicate redox-driven biogeochemical reactions, salt exclusion during ice formation, and continuous to sporadic exchange of river water. Redox reactions were regulated by DO inputs stemming from atmospheric, photosynthetic, and riverine sources. During ice-covered periods dissolved sulfate may be conservative but was generally removed. Manganese and iron concentrations showed phases of production and removal during ice-covered periods, but both were produced overall. Calculated solute fluxes from lake waters alone to the Arctic Ocean may only impact yearly riverine fluxes for solutes that exceed ten times the river concentration prior to ice breakup (e.g., Mn and Fe).</p>
Unmanned Aerial Vehicle Image Dataset of the Built Environment for 3D reconstruction (UAVID3D)
<p>Unmanned Aerial Vehicles (UAV) provide increased access to unique types of urban imagery traditionally not available. Advanced machine learning and computer vision techniques when applied to UAV RGB image data can be used for automated extraction of building asset information and if applied to UAV thermal imagery data can detect potential thermal anomalies. However, these UAV datasets are not easily available to researchers, thereby creating a barrier to accelerating research in this area. </p> <p>To assist researchers with added data to develop machine learning algorithms, we present UAVID3D (Unmanned Aerial Vehicle (UAV) Image Dataset of the Built Environment for 3D reconstruction). The raw images for our dataset were recorded with a Zenmuse XT2 visual (RGB) and a FLIR Tau 2 (thermal, https://flir.netx.net/file/asset/15598/original/) camera on a DJI Mavic 2 pro drone (https://www.dji.com/matrice-200-series). The thermal camera is factory calibrated. All data is organized and structured to comply with FAIR principles, i.e. being findable, accessible, interoperable, and reusable. It is publicly available and can be downloaded from the Zenodo data repository. </p> <p>RGB images were recorded during UAV fly-overs of two different commercial buildings in Northern California. In addition, thermographic images were recorded during 2 subsequent UAV fly-overs of the same two buildings. UAV flights were recorded at flight heights between 60–80 m above ground with a flight speed of 1 m s and contain GPS information. All images were recorded during drone flights on May 10, 2021 between 8:45 am and 10:30 am and on May 19, 2021 between 2:15 pm and 4:30 pm. Outdoor air temperatures on these two days during the flights were between 78 and 83 degree fahrenheit and between 58 and 65 degree fahrenheit respectively. </p> <p>For the RGB flights, UAV path was planned and captured using an orbital flight plan in PIX4D capture at normal flight speed and overlap angle of 10 degree. Thermal images were captured by manual flights approximately 5 m away from each building facade. Due to the high overlap of images, similarities from feature points identified in each image can be extracted to conduct photogrammetry. Photogrammetry allows estimation of the three-dimensional coordinates of points on an object in a generated 3D space involving measurements made on images taken with a high overlap rate. Photogrammetry can be used to create a 3D point cloud model of the recorded region. UAVID3D dataset is a series of compressed archive files totaling 21GB. Useful pipelines to process these images can be found at these two repositories <a href="https://github.com/LBNL-ETA/a3dbr">https://github.com/LBNL-ETA/a3dbr</a>, and <a href="https://github.com/LBNL-ETA/AutoBFE">https://github.com/LBNL-ETA/AutoBFE</a></p> <p>This work was supported by the Assistant Secretary for Energy Efficiency and Renewable Energy, Building Technologies Program, of the U.S. Department of Energy under Contract No. DE-AC02-05CH11231. </p> <p> </p> <p> </p>

Dataset of biodiversity of the Seine nursery over 20 years in a highly disturbed environment
<p>Estuaries are crucial ecosystems where human activities deeply affect numerous ecological functions. The Seine estuary, located on the French coast of the eastern English Channel, is a very dynamic environment where this conflict between the two contrasting backgrounds exists. The Seine watershed is highly disturbed by human activities due to significant industrial development and high population density. The estuary is a historic fishing ground for brown shrimp (<em>Crangon crangon</em>) and various species of flatfish, among which sole (<em>Solea solea</em>) and plaice (<em>Pleutronectes platessa</em>). However, it is a nursery area for fish and plays a crucial role in the life cycle of many demersal and benthic fish and invertebrates.</p> <p>Here we present a survey dataset of biodiversity in the nursery of the Seine estuary and eastern bay of Seine collected using a beam trawl throughout three periods from 1995 to 2019. IFREMER (the French Institute for the Exploitation of the Sea) implemented scientific cruises on coastal nursery grounds aimed at describing the fish population and give an insight into the ecosystem functioning in these areas. The NOURSEINE survey presented here came to existence in this context. The surveys happen at the start of autumn to maximize the catchability of juvenile fish. The beam trawl targets mainly benthic and demersal species over a more than 600 square kilometers study area. The dataset includes abundance and densities of 161 species for 634 hauls performed at around 40 stations each year. These data can be used by fishery scientists and ecologists motivated by earlier stage life of commercial species or by the impact of human disturbances, such as harbor developments, on estuarine communities. They can help in understanding how the nursery functions may change through time and potential human disturbances.</p> <p> </p> <p>Dataset.csv: The data represents the density for the different species encounters in the trawl stations across the 14 years where the NOURSEINE campaign took place. The table contains 22435 rows and 22 columns. Each row corresponds to the density of a species or individuals of the same size in a given haul, and this separation comes from the sorting operation. After each haul, the content of the trawl is emptied on deck, and a total or partial sorting is carried out depending on the volume and homogeneity of the capture. All species, both fish and benthic, are sorted, identified, counted and weighted. Fishes of commercial value and all others flatfish are measured. Fish’s otoliths are collected on the main commercial fish species (sole, plaice, flounder, dab, pouting, large whiting and European bass) and their age group determined later on in the laboratory. In 1999, the sampling was incomplete for technical reasons, and only commercial invertebrates were sampled (King scallop and lobster).</p> <p>Sorting the capture can be separated into three different steps (See pdf figure attached):</p> <p> 1. Total capture weighting: when the hauls are emptied on the deck, the whole capture is distributed in several baskets/box in order to weight it.</p> <p> 2. Fish and large taxa sorting: All fish and large taxa of invertebrates easily identified (edible crab, common spider crab, large cephalopods) are sorted, identified, numbered, measured (for fish) and weighted (total weight per taxa). Depending on the size of the capture, a subsample might be necessary, and the operation is only performed on it. In case visual identification is too difficult (for instance due to a large mud proportion), the capture may be washed using a 5mm sieve. The weight ratio between the total capture and the subsample form a “division” variable that allows the calculation of the density. Another subsampling may be needed if a taxon has a high abundance. In that case, for practical reasons, only a subsample of the individuals are numbered and measured. The weight ratio between the total abundance and the subsample form a “coefficient” variable that is also used in the calculation of the density.</p> <p> 3. Benthic fauna sorting: What is left from the second step is weighted before the sorting operation. All taxa constituting benthic fauna are sorted, identified, numbered and weighted (total weight per taxa). Some taxa may be measured (whelk, scallop). Just like step 2, according to the quantity of benthic fauna, a subsample might be necessary before sorting. All observations are manually recorded on fieldwork paper book before being checked and registered on the NOURSEINE database.</p> <p>All observations are manually recorded on fieldwork paper book before being checked and registered on the NOURSEINE database.</p> <p> </p> <p> </p> <p>Description of the columns found in the dataset</p> <ul> <li><strong>Year</strong></li> </ul> <p>The year when the sampling event took place.

CURE-OR: Challenging Unreal and Real Environments for Object Recognition
<p>As one of the research directions at <a href="https://ghassanalregib.info/">OLIVES Lab @ Georgia Tech</a>, we focus on the robustness of data-driven algorithms under diverse challenging conditions where trained models can possibly be depolyed. To achieve this goal, we introduced a large-sacle (1.M images) object recognition dataset (<a href="https://github.com/olivesgatech/CURE-OR">CURE-OR</a>) which is among the most comprehensive datasets with controlled synthetic challenging conditions. In <a href="https://github.com/olivesgatech/CURE-OR">CURE-OR</a> dataset, there are 1,000,000 images of 100 objects with varying size, color, and texture, captured with multiple devices in different setups. The majority of images in the dataset were acquired with smartphones and tested with off-the-shelf applications to benchmark the recognition performance of devices and applications that are used in our daily lives.

The next frontier: Human settlements in the marine environment
<p>Human settlements have impacted most terrestrial environments on Earth. With a rapidly growing global population, surging demands for resources, and unprecedented alteration to Earth's ecosystems, the conservation of our only suitable habitat is a contemporary zeitgeist. Moreover, humanity's nature for enterprise and exploitation continuously pushes the frontiers of exploration, while the governance associated with expansion beyond terra firma is uncertain and rife with conflict. Though the notion of human expansion into the oceans is becoming more orthodox, we have largely overlooked Earth's oceans as space for human habitat. Here, we build on the case for humanity's future over the marine environment and discuss how exploring this frontier will result in advances for industries, economies, and exploration. The "Blue Acceleration" could transform the nascent phenomenon of marine cities into reality, and we support this notions with a global marine spatial plan to assess the suitability of marine settlements. Our analysis shows that every oceanic basin supports regions for sustainable human settlements. More broadly, we discuss the implications of a human-marine frontier and the benefits that will ensue for science, humanity and our planet. Finally, we argue that the human-marine frontier should be an immediate steppingstone for future exploration, innovation and discovery.</p>
Dataset for semantic segmentation of the laboratory model of manufacturing environment
<p>This dataset includes images and labels used for semantic segmentation of the laboratory model of the manufacturing environment, at the University of Belgrade - Faculty of Mechanical Engineering. The dataset is gathered by using mobile robot RAICO (Robot with Artificial Intelligence based COgnition) and its stereo visual system made from two Basler acA1920-25uc cameras with Fujinon lens DF6HA-1B. The dataset includes close to 430 images with a resolution of 640x360. Images are acquired by both cameras at different mobile robot poses in the laboratory model of a manufacturing environment. Five classes are introduced in the dataset, machines 1 to 4, and a background class. The exact names of the classes are:</p> <p>classNames = ["Machine_1", "Machine_2", "Machine_3", "Machine_4", "Background"];</p> <p>while the labels of the classes (RGB values of label images) are:</p> <p>labelIDs = [ ...<br> 000 000 255; ... % "Machine 1"<br> 000 255 255; ... % "Machine 2"<br> 255 255 000; ... % "Machine 3"<br> 255 000 000; ... % "Machine 4"<br> 255 255 255; ... % "Background"<br> ];</p> <p>Image and label pairs are entitled 1 to 430, and e.g. label 5 corresponds to images 5.</p> <p>This dataset was developed with the support of the Science Fund of the Republic of Serbia, Grant No. 6523109, AI - MISSION4.0, 2020-2022.</p>
