Arctic LTER site, station Kuparuk River, study of water temperature (mean maximum) in units of celsius on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Arctic LTER (ARC) contains water temperature (mean maximum) measurements in celsius units and were aggregated to a yearly timescale.

Mobile Ocean Bottom Seismometer Instrument (MOBSI) data from Arctic rivers, lakes, and seas
<p>We collected the data using the Mobile Ocean Bottom Seismic Instrument (MOBSI). The MOBSI is portable (9 kg) and consists of a watertight, heavy-duty pressure housing (diameter 30 cm, height 35 cm) containing a three-component, broadband seismic sensor. There are three channels (two horizontal and one vertical) recorded by the built-in data logger to monitor ambient seismic noise. Deployed by a steel cable from a small boat or zodiac, the device was lowered to the bottom of the water bodies or the top of the beach area (if present). The device recorded ambient seismic noise for a few minutes before being retrieved and moved to a new location. The steel cable was outfitted with a communications cable, which allowed for live data analysis and quality control via a shipboard monitor. This ensured that the tilt of the instrument was correct (less than 5 degrees) and that the deployment time was sufficient. We stopped data collection when the "real-time" H/V ratio was stable, i.e., not changing with time. For all soundings, the sampling frequency was set to 100 samples per second. The MOBSI data was recorded in an internal RAW format that was converted to MINISeed format. In this paper, we present MOBSI data for seven survey lines from the Russian and the Canadian Arctic. The Banja Lake and Lena River profiles are situated in the Lena Delta, northeastern Siberia, Russia. Ivashkina Lagoon is located along the southern coastline of the Bykovsky Peninsula, northeastern Siberia, Russia. The Tuktoyaktuk profiles are located north of Tuktoyaktuk Island (Northwest Territories, Canada) in the Canadian Beaufort Sea. The survey lines presented in this manuscript are the following:</p> <p>Profile A-A' (Banja Lake): 8 soundings</p> <p>Profile B-B' (Banja Lake): 9 soundings</p> <p>Profile C-C' (Banja Lake): 9 soundings</p> <p>Profile D-D' (Lena River-Samoylov Island): 9 soundings</p> <p>Profile E-E' (Lena River-Chay-Tumus): 16 soundings</p> <p>Profile F-F' (Tuktoyaktuk Island): 10 soundings</p> <p>Profile G-G' (Tuktoyaktuk Island): 9 soundings</p> <p>Profile H-H' (Ivashkina Lagoon): 20 soundings</p> <p>The Excel file "MOBSI_soundings.xlsx" provides an overview of all the soundings, whereby each tab is split by the survey line. The latitude, longitude, water depth, and recording time for each sounding is provided.</p>
Arctic Tundra Flux Study in the Kuparuk River Basin (Alaska), 1994-1996
CO2 and water vapor fluxes and ecosystem characteristics were measured at 24 sites along a 317-km transect from the Arctic coast to the latitudinal treeline in Alaska during the growing seasons of 1994-1996. The sites were stratified to sample the ranges of climate, physiography, soil moisture, and vegetation type within the region. Our main objective was to understand what factors control variations in CO2 and water vapor exchange across the region. We therefore developed a spatially extensive approach of documenting fluxes for 1-2 weeks at each of the sites in order to study as many sites as possible during the middle of the short arctic growing season, when plant phenology is most comparable among different vegetation types and climatic regions. This allowed us to compare, with some replication, a given vegetation type across different provinces and climatic zones, as well as multiple vegetation types within a given geographic area.
ABoVE: Seasonal Dissolved Gases and Isotopes in Arctic Alaska Rivers
This dataset provides dissolved carbon dioxide (CO2) and methane (CH4) concentrations alongside their stable and radiocarbon isotopic compositions within the Arctic Sagavanirktok and Kuparuk River watersheds located on the North Slope of Alaska. The data were collected during the spring, fall, and summer seasons in 2022. In field separation of the bulk gaseous components (N2, CO2, and CH4) from the liquid phase was achieved using a degassing membrane contactor. Laboratory isotopic analyses were conducted at the W. M. Keck Carbon Cycle Accelerator Mass Spectrometer facility at UC Irvine. This collection aims to provide insights into the seasonal dynamics of greenhouse gas emissions in these critical Arctic environments, thereby contributing valuable information for climate change research and monitoring programs. The data are provided in comma separated values (CSV) format.
