Eggshell thickness was measured at the egg equator and poles (sharp pole and blunt pole) for 12 avian species. Eggshell thickness was related to egg morphometrics (egg length and width), embryonic development, egg status, and mercury contamination. Individual eggshells each have up to 3 thickness measurements, linked by the eggshell identification. Each measurement has the corresponding egg length, egg width, egg status, mercury concentration, and nest identification. Additionally, eggshell thickness was measured at 5 equally spaced positions along the longitude of the egg (sharp pole, quarter egg, half egg, three quarter egg, and blunt pole) in a subset of Forster's tern (Sterna forsteri) eggs. These data support...

The "published" dataset includes 11,000 published measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil, dry), percent of soil organic matter (%OM, loss on ignition, LOI), percent of soil organic carbon (%SOC, calculated using the Redfield's number), RHgC (Hg to carbon ratio), and age (YBP) from 13 published studies conducted throughout the arctic and subarctic.

This dataset includes the field measurements and laboratory analyses of surface water, seston, fish tissue, and sediment samples collected from Bighorn Lake, within Bighorn Canyon National Recreation area (BICA), during high flow (July 2015) and low flow (August 2016) conditions. The study area includes 7-9 sampling sites that follow a transect spanning the entire length of the reservoir from the Bighorn and Shoshone River inflows to the afterbay and tailwater below Yellowtail dam. Multiple samples were collected at each sampling site and usually included the top 2 cm of sediment at the sediment/water interface, 2 meters above the sediment/water interface, and 2 meters below the reservoir surface. Microbial samples...
