Data for assessing the status of sediment toxicity and macroinvertebrate communities in the Eighteenmile Creek Area of Concern, New York, 2014

Data from 10-day sediment toxicity tests of bed sediments from the Eighteenmile Creek Area of Concern and Oak Orchard Creek (nearby reference stream), Niagara and Orleans County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Sediment samples were collected from five sites on each stream. Bed-sediments were collected from depositional areas using a petite Ponar (0.03 square meter) dredge. At each site, approximately five grabs were composited into a bucket, mixed, and a 4-liter (L)...

Morphology data for Ciscoes (Coregonus, subgenus Leucichthys) collected in the Great Lakes Cisco Project

This dataset contains morphological information for Ciscoes (Coregonus, subgenus Leucichthys) collected from the Great Lakes as part of the "Great Lakes Cisco Project". The project was initiated in 1950 by Stanford H. Smith, who was a Fishery Research Biologist in the then U.S. Bureau of Commercial Fisheries. The dataset includes 16 morphometrics (linear measurements) and one meristic (count of gill rakers) for Ciscoes, together with biological data (i.e., length, weight, sex, and maturity), sampling location, and date of collection. Consult Koelz (1929) and the "Morphology of Ciscoes" section in Eshenroder et al. (2016) for descriptions of how measurements and counts were made in the then "Ann Arbor Laboratory"...

Development of an age estimation method for Grass Carp from North America

The development of a reliable method of age estimation for Grass Carp is necessary for the successful management of this invasive species. Multiple federal and state agencies with assistance from commercial fishers collected adult Grass Carp from 2012 to 2018. Ossified parts were collected from these fish, and age estimates from them were compared to develop an age estimation method. Here we provide the data used in that effort.

Lake Ontario. Glaciated limestone laid bare by wave action at Pillar Point, New York. The bluff is composed of till.

Lake Ontario. Glaciated limestone laid bare by wave action at Pillar Point, New York. The bluff is composed of till. Besides the parallel striation, the surface exhibits an irregular group of scratches in a different direction. These were supposedly caused by the stranding of an iceberg. Circa 1895.
