Long-term snow chemical composition monitoring - Hansbreen glacier (Hornsund) - raw data

<p>During the accumulation season, snow samples were taken on Hansbreen Glacier. Several times per season. Snow samples were collected in polyethylene sterile bags and transported to the Polish Polar Station Hornsund. After melting at room temperature, the pH, conductivity and chemical composition (major ions) were analysed in the chemical laboratory of the Polish Polar Station.<br> Snow chemical composition: major ions, HCO3-, pH, conductivity</p> <p>Presented data from 2015 to 2019</p> <p>The data has not been checked, which means that it is raw data.</p> <p>Principal Investigator (PI) Adam Nawrot</p>

Data for: Should I breed or should I go? Manipulating individual state during migration influences breeding decisions in a long-lived bird species

<p>Documentation of Carry-Over Effects (COEs), defined as effects resulting from events that occurred in a previous time period, has largely been observational and understanding of specific mechanisms underlying COEs is still lacking. To investigate this, we simulated an environmental perturbation during the spring migration of a long-lived bird species and looked at the subsequent effects on various breeding parameters. We captured female greater snow geese (<em>Anser caerulescens atlanticus</em>) on their spring staging sites and maintained individuals in captivity for up to four days before releasing them. We re-observed females 3000 km North, on their Arctic breeding grounds, to estimate their breeding propensity (i.e., probability of initiating a reproductive event for a given year), and measure their arrival date, laying date, clutch size, and nesting success. Only proxies of breeding propensity were affected by our manipulation, which decreased as the time spent in captivity increased. However, females were able to overcome the effects of captivity in two out of the three years of experimentation with normal or good environmental conditions at the breeding site. When facing the additional challenge of poor environmental conditions, many individuals manipulated during migration apparently curtailed their reproductive effort by skipping breeding. This experiment is the first to show that breeding propensity is an important parameter affected by COEs resulting from stressful events prior to reproduction in long-lived species.</p>

Observations of Autumnal Cooling in a Large Estuary: The Glider Data from Long Island Sound in 2014

<p>This data file is a component of the data used in a paper to appear in the Journal of Geophysical Research in 2023 entitled &quot;Observations of Autumnal Cooling in a Large Estuary&quot; by Amin Ilia, Grant McCardell, Kay Howard-Strobel, and James O&#39;Donnell.&nbsp; The data file contains the measurements from a Slocum Glider (V1) from Webb Research used in the paper. The data is in&nbsp;a MATLAB binary (.mat) file as a structure variable with a field&nbsp;MetaData containing&nbsp;some notes, and data in&nbsp;<br> &nbsp; &nbsp; SampleTimeEST- the date and time of the sample (EST) in MATLAB&#39;s datenum() format<br> &nbsp; &nbsp; Pressure_dBar - the pressure (or&nbsp;equivalently depth in m) that the sample was acquired&nbsp;<br> &nbsp; &nbsp; Temperature_C - the water temperature in Celcius<br> &nbsp; &nbsp; PracticalSalinty - the practical salinty<br> &nbsp; &nbsp; LatitudeDeg- the latitude of the sampling location (deg)<br> &nbsp; &nbsp; LongitudeDeg - the longitude of the sampling location (deg east)</p> <p>The paper&#39;s abstract is:&nbsp;</p> <p>Long Island Sound (LIS) is a large estuary on the eastern United States coast. Seasonal variations&nbsp;<br> in solar insolation and wind create an annual water temperature cycle that impacts circulation&nbsp;<br> and biological processes. The waters warm from March-February until August-October and then&nbsp;<br> begins to cool. Ship surveys show that the vertical temperature structure becomes uniform during&nbsp;<br> this season when the area experiences low air temperatures and high winds. However, there have&nbsp;<br> been no observations that resolve the temporal evolution of the vertical structure of temperature&nbsp;<br> during these cooling periods because conditions inhibit ship operations. We report glider&nbsp;<br> measurements of the vertical structure of water temperatures and salinities from October 22 to&nbsp;<br> November 4, 2014, in eastern LIS. We find that 20m of water can cool at approximately 0.5&nbsp;<br> C/day intervals of cold air and strong winds. We use the data to estimate heat content tendencies&nbsp;<br> and infer surface fluxes. We also estimate the surface heat fluxes using buoy-mounted&nbsp;<br> instruments and the COARE 3.0/3.5 formulae and show they are consistent. Using the buoy&nbsp;<br> fluxes and the products of an operation regional model, we show the agreement with the heat&nbsp;<br> budget fluxes is best when the closest buoy and the model results are used. This suggests that&nbsp;<br> resolving the temporally and spatially structure of the wind field is crucial to the accurate&nbsp;<br> simulation of the temperature variability in LIS. These intervals of very rapid cooling can lead to&nbsp;<br> significant density gradients between LIS and the shallow bays and marshes that surround it.</p>
