Exceptional monitoring efforts have established a shift from Arctic to Subarctic climate regime within the last decade (Grebmeier et al. 2006). Building on the existing 30-year record of direct observations on the water column and benthic macrofauna, I will extend this record back to the last glacial maximum using geologically young fossil material (<10,000 years old), including both skeletal death assemblages accumulating in the seabed, and recently buried fossils from sedimentary cores. This longer time perspective on the Bering shelf since the Last Glacial Maximum will open the door to basic research questions related to (1) the preservation and taphonomy of fossil remains in high latitudes (live-dead analysis, shell age-dating), (2) changes in seasonality (molluscan sclerochronology), and (3) biotic response to climate change under both natural and anthropogenic…
Please define the terms listed below: 1. Physical Geography is the study of the earth’s physical features, like mountains, soils and waters. 2. Human Geography is the study of the way people have had an impact on the Earth’s physical features, like constructing dams or buildings. 3. Absolute location is a location on the earth that can be found by using mathematical coordinates. 4. Latitude is one of the measures used for absolute location. It is a measurement that goes from north to…
Differential heating occurs when the earth leans and rotates around the sun that heats the globe year long. Because of so many changes of solar radiation, lower latitudes have more energy than the higher latitudes from the sun. Some locations on the same line of latitude will have different weather depending on how close or far they are to the oceans. Also lakes and rivers reduce the heat temperature because of the large amount of water they hold. When the atmosphere heats up it creates…
Temperature is higher at city A and lower at city B. b.) Is the season winter or summer? How are you able to determine this? The season is summer. In summer temperature near the city is higher than that in the main land c.) Describe the position of the isotherm six months later. Temperature will be lower in A and higher in B. this is because it will be winter and temperature in the land will be higher than that in the sea. The graph will be on top of A and below B. 6.) Based on…
To see the similarities and differences between wind patterns in the Northern and Southern Hemispheres alongside with explaining the major wind belts. Material: • Map of North America with longitude and latitude • Drawing compass Procedure: 1. View the map from the lab given. The map represents the barometric pressures at 5000 feet in North America on a precise day in February. 2. Use the Web to get another map of North America that covers the same approximate area shown in the map given in the…
The graph above compares the optimal depth for latitudes 21.4S 32.4E, 21.4S 55.3E, and 21.4S 65.3E on the given dates. Latitude 21.4S 32.4E is located in Africa between Zimbabwe and Mozambique, Latitude 21.4S 55.3E is located on Reunion island, and Latitude 21.4S 65.3E is located in the Indian Ocean. Biomass burnings alter the optical depth in Africa, whereas volcanic activity is responsible for the variations in optical depth on Reunion Island. According to the graph, biomass burnings create a…
1. Identify a city or area of a country within your new region: Seattle, Washington 2. Location: Describe the absolute and relative location of your city or area within your new region. Support your description with current examples in 2 to 3 sentences. Include citations for your resources using APA style guidelines as needed. Seattle is located at latitude 47.60’N, longitude 122.33’W (Worldatlas, 2015). Seattle is located on Puget Sound which connects to the Pacific Ocean (Worldatlas, 2015).…
to the September/ March equinox. It then moves along to the December solstice. During the December solstice the sun rises to the south of the east and sets to the south of the west. Right after the December solstice the sun starts to drift back into its yearly cycle (Changing Sun, Changing Climate?, 2014). The sun repeats this process every year and this is how we get the different seasons. Depending on what area of the earth you are on there will be different outcomes. Anywhere around the…
