Measure ice thickness with a tape. Chainsaw Cut a byinch square into the ice. When it floats, tilt or lift it and measure. Ensure the square goes back into the hole to refreeze, and add a stick to flag the hazard. Homemade test pole A 2″-dia. hardwood dowel, 60″ long, makes for a quick ice-testing poker stick. Pre-drill a 3/ In , the European Space Agency launched the CryoSat-2 satellite, which carries the Synthetic Aperture Interferometric Radar Altimeter (SIRAL). Data from this instrument are converted into maps of sea ice thickness—a useful tool for tracking change over time and for monitoring winter season ice .
The lower part of Figure 6 shows two plots comparing the ice thickness profile along two tracks: in red is the ice thickness profile produced from the data with the tomographic sounding technique and in blue is the ice thickness profile made from the data using the depth sounding technique. on ice thickness data to a wide range of numerical ice thickness predictors. This paper compares methods for predicting static ice formation, in which the flow velocity plays no role. The threshold current for static ice formation is about m/s (USACE, ). 2. The Ice Growth Process and How it Affects Predictions of Ice Thickness.
The ice sheet varies in thickness, with the East Antarctic sheet much higher than the West Antarctic sheet. On average, the ice is more than . Checking ice thickness. Before heading out on ice: Temperature, snow cover, currents, springs and rough fish all affect the relative safety of ice. Ice is seldom the same thickness over a single body of water; it can be two feet thick in one place and one inch thick a few yards away. Check the ice at least every feet. Ways to check ice.

Ice thickness measurements are generally taken near the beginning of the month from October to June. Readings taken near the end of the month are appied to the following month.
To view historical readings please select the month/year below. The Pan-Arctic Ice-Ocean Modeling and Assimilation System (PIOMAS) is a coupled ice and ocean model with sea ice thickness data available over the satellite era (from ) (Zhang and Rothrock, ).
PIOMAS has been widely validated against sea Ice thickness data. book thickness data sets (such as ICESat), and its uncertainties are addressed in Schweiger et al.
The along-track thickness product includes the various sea ice thickness estimates, ancillary data, and individual (random and systematic) uncertainty estimates to enable more comprehensive evaluation of the data for the more advanced user.
Two data files are provided for each associated ATL10 granule: (i) A raw along-track dataset posted at. The Canadian Ice Thickness Program has two data collections that users can access anytime online: Ice Thickness Program Collection, to [XLS; MB] | Metadata; Ice Thickness Program Collection, Fall to [XLS; KB]; The ‘Original Ice Thickness Program Collection’ contains ice thickness and snow depth measurements for sites.
The ambitious goal of the "Snow and Ice Data Book" (SIDB) is to report on experiences in winter maintenance from some 30 countries.
This tool was launched more than 15 years ago and its updated version, published every 4 years at the time of the International Winter Road Congress, is always a.

Ice Thickness Chart. WARNING: Always be cautious. If you are unsure if the ice is safe, don’t take your chances. Exercise extreme caution when using vehicles on ice and go with someone who’s familiar with the area.
As the chart above shows, ice needs to be at least 8 inches thick to hold a small pickup ruck. Sea ice thickness can now be measured using data from the European Space Agency CryoSat-2 satellite, which was launched in It is currently too early to say exactly how this years maximum ice amount will compare to previous years because Arctic sea ice continues to.
Page 63 C. Remove ice thickness probe • Compress the hinge pin on the top of the ice thickness probe. • Pivot the ice thickness probe to disengage one pin then the other.
The ice thickness probe can be cleaned at this point without complete removal. If complete removal is desired, disconnect the ice thickness control wiring from the control.
Abstract: Ice thickness data collected between and using a coherent ice penetrating radar system developed at the University of Kansas have been combined with data collected by the Technical University of Denmark in the s to produce a new ice thickness grid for Greenland.
Cross-over analysis was used to assess the relative accuracy of the two data sets and they were. Large data plate will be placed on the back of the unit. Small data plate will be placed by the service valves.

Capable of retrieving daytime and nighttime sea and lake ice thickness under both clear and cloudy sky conditions IDPS Sea Ice Concentration is an intermediate product (IP) Algorithm computes ice fractions based on ice and water tie points determined from VIIRS I1 ( µm) and I2 ( µm) reflectance and surface temperature from the VIIRS.
The second table (TT, Fig. 1) includes ice thickness data (mean and/or max; TT9–TT12) averaged over surface elevation bands by given lower and upper boundaries (TT5 and TT6) from ice thickness maps or Digital Elevation Models (DEMs).The third table (TTT, Fig. 1) contains point data including a point ID, related coordinates, the elevation at the surveyed point, as well as the thickness.
The map, animation and graph illustrate the sea ice thickness in the Northern Hemisphere, excluding the Baltic Sea and the Pacific. The data is based on DMI ’s model calculations. The map is updated on a daily basis. In order to get a true picture of the state of the sea ice, it is necessary to determine both its extent and its volume.
A new NASA study says that an increase in Antarctic snow accumulation that be years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. Accurately monitoring sea ice is increasingly important given the rapid and extreme changes that are occurring in the Arctic.
Indigenous communities have monitored Arctic sea ice thickness for centuries, but it has only been scientifically monitored on a semi-regular basis since the mid-twentieth century (Wadhams, Wadhams, P. The mean fraction of usable ice thickness data: N usable /(N usable + N missing), for all months studied, was 78%.
The minimum fraction of usable data was 26%, with an equivalent uncertainty of ± km 3 (16%), which occurred in November when sea ice. This will probably solve your problem, most likely a dirty or malfunctioning ice thickness probe.

ICESat Satellite data: ICESat laser-altimeter freeboard measurements and ice thickness estimates are available sporadically from to How is the data set organized.
As seen above, the ice thickness data comes from many different sources, each. If, for simplicity, we assume the average annual thickness to be the mean between the annual thickness at the top and at the bottom (about eight inches), this still gives an age of less than years for the foot-thick ice sheet to form under uniformitarian conditions.accretion that is reported in papers that use ARA data is not a good measure of the load of ice on the wire.
The determination of the equivalent radial ice thickness t from field measurements of ice samples in freezing rain storms is presented in Figure Application to weather data.Ice Thickness Program Collection, The Ice Thickness Program Collection contains ice thickness and snow depth measurements for 11 sites.
Measurements are taken at approximately the same location every year on a weekly basis, starting after freeze-up when the ice is safe to walk on, and continuing until break-up or when the ice becomes unsafe.
