title: High Pressure Torsion tests on two types of rail sand under wet contact conditions

description: This data set contains the data of sanded High Pressure Torsion (HPT) tests under wet contact conditions.Tested were two types of rail sand, which are used to increase friction in wheel-rail contacts.Please see the following paper for a detailed description of experiments:"B. Suhr, W. A. Skipper, R. Lewis, and K. Six, “Mechanisms of Adhesion Increase in Wet Sanded Wheel–Rail Contacts—A DEM-Based Analysis,” Lubricants, vol. 13, no. 7, 2025, doi: 10.3390/lubricants13070314."

The material tested was two types of sand used in railways, called AT sand (used in Austria) and GB sand (used in the UK).The sand grains used in the tests nearly had the same size, passed through a 1.2mm sieve but did not pass a 1.18mm sieve.The HPT top and bottom specimen were made of R260 grade rail. To ensure repeatability and a realistic state of both top and bottom specimen, they are run together to fully condition (shakedown) the surfaces. In each test, roughly the same weight of sand grains was used, which resulted in placing ten sand grains manually.After placing the grains, water is added and a normal stress of 900MPa is applied, followed by a shearing of 0.4mm keeping the normal stress constant.The folder HPT_measurements contains the measurement results in txt format.Tests number 2,3,4 are conducted with GB sand, and tests number 5,6,7 are conducted with AT sand.In each file, column 1 is the time [s], column 2 is the shear displacement [mm] and column 3 is the adhesion coefficient [-].

After conducting the tests, a non-contacting imaging and measuring tool named Alicona InfiniteFocusSL was used to take 3d scans of the surfaces. Both top and bottom specimen were scanned. First scans were taken directly after the test, with sand clusters still attached to the steel surface. Second scans were taken after cleaning the surfaces showing indents caused by the sand clusters.The images obtained can be found in the folder AliconaImages.File names are build using the test number, T (top) or B (bottom) and _Cleaned for cleaned surfaces.Thus: 2_B.jpg: GB sand, Bottom specimen, first scan with sand clusters on the the surface2_B_Clean.jpg: GB sand, Bottom specimen, secon scan after cleaning the surface

Abstract:
In January 2004, investigators from CUNY-Staten Island (Richard Veit, Marie Caroline Martin) and Duke Marine Lab (David Hyrenbach) embarked on a research cruise spanning through the Madagascar Channel and across the Southern Indian Ocean. The cruise departed from La Reunion Island, and visited Madagascar, the French territories of Mayotte, Crozet, and Kerguelen, and returned to La Reunion. During this cruise, we surveyed marine birds and mammals across a large-scale gradient of ocean productivity and water mass characteristics, spanning from tropical to Antarctic waters (from 12 to 60 degrees S).

Aerial surveys of marine birds have been conducted annually since 1992 by the Puget Sound Ambient Monitoring Program (PSAMP) staff during both a summer (July) and a winter (December to early February) survey window, sampling some part of every portion of the marine shoreline of the inner marine waters of Washington state by two strata: nearshore (&lt; 20 meters in depth) and offshore (&gt; 20 meters in depth). 

The datasets are split by season (summer or winter) and year.

Abstract:
On 6 July to 9 August 1992, as part of a larger study, Alaska harbor porpoise (&lt;i&gt;Phocoena phocoena&lt;/i&gt;) abundance was investigated during an aerial survey off Kodiak Island. Employing a Twin Otter as the survey platform, the third of three identical sawtooth tracklines was flown at an altitude of 152.2 m (500 ft) and at an airspeed of 185 km/h. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Density of harbor porpoises was calculated using line transect estimates based on perpendicular distances of sightings to the cruise track of the airplane. On average, porpoise group size and density off Kodiak Island was 1.41 (SE = 0.13) and 1.85 groups/100 km2 (SE = 6.03).
