Genre/Form: Scientific atlases Maps Atlases: Additional Physical Format: Lake ice climatic atlas, Great Lakes, / [Ottawa]: Canadian Ice Service, © A winter () set of 1973-2002 book ice charts was digitized, and a multi-winter statistical analysis of the climatology of the ice cover concentration was completed.

The results of this analysis are published here as an electronic NOAA Great Lakes Ice Atlas. The Great Lakes Ice Atlas summarized ice cover for the periodwith addendums in a separate report forin addition to providing a number of statistical products.

Using the same methods, the original ice charts for through present were processed and added to. Lake Ontario was selected as the study site for this case study to explore the statistical relationship between regional temperatures and lake ice conditions within the Laurentian Great Lakes ing to Environment Canada (, p.9), Lake Ontario has a “maximum depth of m located in the southeastern part of the northeastern end of the lake Author: Micah J.

Hewer, William A. Gough. In particular, the middles of Lakes Ontario and Lake Michigan remain on average % ice-free at winter maximum. In contrast, Lake Erie, a shallower lake, is normally over 70% ice covered by late winter. On the bottom is a time series of the annual maximum ice cover averaged over all of the Great Lakes from to Data Used in Regional Charts.

For this edition of the atlas, CIS data was used exclusively for the entire period. In the previous edition () charts from NIC were incorporated for the period CIS remains grateful to GLERL for their contribution in digitizing the original ice charts for the period /73 to /95 and without their assistance, this atlas could not have been.

Ice and snow cover the Great Lakes March 9, NASA. Ice coverage. Lake Superior could have little to no open-lake ice cover during a typical winter Great Lakes the next 30 years, according to GLISA.

Great Lakes, chain of deep freshwater lakes in east-central North America comprising Lakes Superior, Michigan, Huron, Erie, and are one of the great natural features of the continent and of the Earth. Although Lake Baikal in Russia has a larger volume of water, the combined area of the Great Lakes—s square miles (, square.

The series includes "Sea Ice Climatic Atlas - 1973-2002 book Coast of Canada " and "Sea Ice Climatic Atlas - Northern Canadian Waters " (available summer ). The ice years (winter of ) through (winter of ) have been used for this publication that covers a climatological time period of 30 years, the standard.

Beautiful. Introduction [2] The timing of lake ice breakup has been of interest for centuries because of its importance for transportation and fishing [Adams, ].It is of critical ecological importance for lakes because the disappearance of the ice cover has a drastic effect on the underwater light climate [Leppäranta et al., ], nutrient recycling [Järvinen et al., ] and oxygen.

The AMIC, while important, does not contain information on the duration of ice cover. A recent winter climatology of Great Lakes ice cover includes daily lake-averaged ice cover for each Great Lake.

The daily lake-averaged ice cover is used in this study to calculate a seasonal average ice cover. GREAT LAKES ENVIRONMENTAL RESEARCH LABORATORY. These links to the Great Lakes Coastal Forecasting System -- Nowcast/Forecast pages include: current observed ice cover, wind, and air temperature; model-derived ice thickness, ice velocity, vessel icing, surface currents, and water temperature.

39 Figure Observed historical annual average Lake Superior water levels (m, ft) for. In recent years, warmer surface water temperatures in the Great Lakes have contributed to lower water levels by increasing rates of evaporation and causing lake ice to form later than usual (see the Lake Ice indicator), which extends the season for evaporation.

1 Lower water levels in the Great Lakes forced ships to reduce their cargo tonnage. Climate Atlas Version 2. The Climate Atlas of Canada was launched in Apriland quickly became a go-to resource for Canadians seeking information about climate change and its national, regional, and local impacts.

On Jwe released a major update to the atlas, which improves and expands the tools we offer. This dataset is distributed by the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL).

The atlas contains data on over digitized Great Lakes ice charts for winters from to and three types of analysis products.

The first analysis product includes ice charts of the following: dates of the first reported ice. Genre/Form: Atlases: Additional Physical Format: Online version: Rondy, Donald R. Great Lakes ice atlas. Detroit, Lake Survey Center, Limnology Division, Annual maximum ice coverage (AMIC) is defined as the greatest percentage of surface area of a lake covered by ice each winter for the Great Lakes.

Figure 4 shows the spatial distribution of the yr (–) mean annual maximum ice cover. Electronic atlas of Great Lakes ice cover, winters | NOAA electronic atlas of Great Lakes ice cover, winters Presents a set of digitized, composite ice charts for the Great Lakes for a winter period ().

Ice data represent "a blend of observations from different data sources (ships, shore, air craft. Lake levels The paleo Great Lakes underwent a series of stages, or levels.

These stages occurred because (1) the crust was rebounding (rising) as the weight of the ice was slowly being removed, (2) the retreating ice sheet was uncovering lower and lower outlets for the lakes, and (3) the outlets themselves were being cut down by the water leaving the lakes.

This is the earliest ice on some of the Great Lakes in at least 40 years. According to the Great Lakes Environmental Research Laboratory, on Novemthree of Michigan’s Great Lakes had ice starting to form.

Lake Superior and Lake Michigan were one-half percent ice covered, while Lake Huron had one percent ice. U.S. Climate Atlas. These maps are based on the new nClimDiv (New Climate Division) dataset which uses daily observations of temperature and precipitation from o stations in the U.S.

NCEI scientists are using new methodologies to quality control the daily data, summarize the daily data into monthly values, and creating maps to visualize the information. Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7, sq mi, 18, km 2), although it exceeds Lake Erie in volume ( cu mi, 1, km 3).It is the 13th largest lake in the its islands are included, the lake's shoreline is.

Great Lakes High Stakes ; Ice shapes economy, identity of Lake Superior’s coastal towns. But it’s disappearing: ‘Culture is defined by how the world around us looks — and now that’s.

Third Coast Atlas is an expansive attempt to define the Great Lakes region and re-evaluate it as a place with a story to tell beyond its constituent cities. Editors Charles Waldheim, Mason White. The majority of lakes on Earth are freshwater, and most lie in the Northern Hemisphere at higher latitudes.

Canada, with a deranged drainage system, has an estima lakes larger than 3 square kilometres ( sq mi) and an unknown total number of lakes, but is estimated to be at least 2 million.

Finland haslakes square metres (5, sq ft) or larger, of which. The atlas contains data on over digitized Great Lakes ice charts for winters from to and three types of analysis products. The first analysis product includes ice charts of the following: dates of the first reported ice, dates of the last reported ice, and ice duration for each winter, as well as, the maximum, minimum and average.

Amazingly, a single lake holds as much fresh water as all the Great Lakes combined – Lake Baikal. This rift lake in Siberia has a maximum depth of 5,ft (1,m). For comparison, the largest of the Great Lakes (Lake Superior) is only 25% as deep, with a maximum depth of 1,ft (m).

Lake Baikal is unique in a number of other ways too. Reductions in winter ice cover lead to more evaporation, causing lake levels to drop even farther. While the graph indicates large year-to-year variations, there is a clear decrease in the extent of Great Lakes ice coverage, as shown by the black trend line.

Image Source: updated from Assel1 References 1. [] Assel, R. Normal ice cover maps, from the NOAA Great Lakes Ice Atlas, were interpolated to yield daily patterns and converted to a Mercator projection with a km grid resolution used for the satellite-derived surface temperature maps.

The lakes also act like giant humidifiers, increasing the moisture content of the air. In the winter, this moisture contributes to heavy snowfall known as “lake effect” snow. Instruments on satellites provide excellent imagery documenting summer and winter weather in the Great Lakes Region.

The interactive Fishing Atlas map shows contours for county and state lakes along with 1, fish structure locations. It also includes road maps, lakes amenities and topography. It also includes road maps, lakes amenities and topography. Icy lakes and rivers make a significant footprint on the Arctic landscape.

Though widely dispersed, lakes cover as much as 40 to 50 percent of the land in many parts of the Arctic, and seasonal lake and river ice covers roughly 2 percent of all of Earth’s land surfaces.

Climate Trends in Great Lakes Ice Cover. The Great Lakes ice atlas data indicates that a trend for below average ice conditions persisted over the entire Great Lakes from to (Figure 1). However, more data needs to be collected and analyzed before researchers will know if a lower ice cover regime has started.

Accurate representations of lake-ice-atmosphere interactions in regional climate modeling remain one of the most critical and unresolved issues for understanding large-lake ecosystems and their watersheds. To date, the representation of the Great Lak. water and more opportunity for lake-effect precipitation.

Snow, climate change and land use change could therefore result Ice Cover and Lake Temperature Lake temperatures have been increasing faster than surrounding air temperatures.
