LAB ACTIVITY: WHAT’S BEHIND SEA LEVEL RISE? A Since changes in the ocean are known to strongly influence the ice sheets, our work on this project is critical to obtaining the best estimates of future sea level. Sea ice has a bright surface, so much of the sunlight that strikes it is reflected back into space. Greenland. Does it matter whether the ice is on land or in the ocean? Climate, Atmospheric Science & Physical Oceanography (CASPO) Tide gauge stations from around the world have measured the daily high and low tides for more than a century, using a variety of manual and automatic sensors.

Familiarity with ArcMap and ArcCatalog; downloading data and projecting it into a common coordinate system; basic geoprocessing; basic familiarity with Python scripting; creating hillshades; working with the attribute table. Even though sea ice occurs primarily in the polar regions, it influences our global climate. Sea level is the average level of the sea after calculating the short-term variations due to wind waves. NOAA Sea Level Rise Viewer. Exploring the limitations of the precision of certain spatial analysis; the difference between raster and vector data; comparison of different geographic areas and the sensitivity of their coasts; effective communication of results with maps. First, water is increasingly invading coastal areas, causing soil erosion and threatening farmland, housing or recreation areas. Global sea level rise began around the start of the 20th century. As Antarctica melts, it will reach the larger sheets that are more inland. They will collect data, graph their results, and interpret their findings. Discuss climate change and sea-level rise as a class. The researchers found one silver lining in their analyses: Curious as to whether past regulations on pollutants have had a significant effect on sea-level rise, the team focused on perhaps the most successful global remediation effort to date — the Montreal Protocol, an international treaty ratified by 197 countries in 1989, that effectively curbed emissions of ozone-depleting compounds worldwide. Clearly, sea level rise is something that is already affecting people and will continue to do so. There are two parts of this lab. According to maps created by the Bay Conservation and Development Commission for the San Francisco Chronicle (Kay, 2007), a 1 meter Their weight will make them melt faster than smaller ice sheets have in the recent past. A simple science fair project to investigate the effect of sea ice (ice in the ocean) versus terrestrial ice (ice on land). This is the third in a series of stand-alone GIS exercises that introduce students to using Python Scripting for ArcGIS. Second, as average global temperatures increase, arctic glaciers and ice caps melt, adding additional volume to ocean water levels. Sea-level rise projections were first included in the Comprehensive Assessment of Climate Change Impacts in Maryland that was part of the 2008 Plan of Action of the Commission on Climate Change. Sea level rise is one of many destructive impacts of climate change, and the melting of the world’s two ice sheets – Greenland and Antarctica – is one of the largest contributors to rising oceans. In … Photo: NASA Go to lesson; 0. Students are also assessed on a workflow and letter summarizing what they did and learned in the lab. Flooding has increased by an average of 233% in the last 20 years. Do sea levels rise when ice melts? Lab Instructions . Nearly 40% of the US population lives along the coast. The sea level rise projections in Fig. For a video on this topic featuring the same activity in this lesson plan, click here. In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. All three contributors to sea level rise can be attributed to the warming of the Earth system. Under drone radar, Fort De Soto Park becomes living lab for sea level rise TIERRA VERDE — Across the road from a snack shack in Fort De … 1. As part of this effort, Donald Slater has led the development of projections of glacier retreat in Greenland. This will allow you to determine the places where sea level is rising the fastest. This video was produced by Rasa Juras, an undergraduate at the University of St Andrews on behalf of GeoBus. The five categories included in the process are. Creative Commons license unless otherwise noted below. In this activity, students will design an experiment to find out. Sea level rise is increasing the exposure of natural ecosystems and the built environment to extreme weather events, high-tide flooding, storm surge, and coastal erosion. The ramifications Our version is slightly modified to to include a secondary shoreline analysis of an area in Asia as well as a Python component. This lab is modified from Barbara Tewksbury's excellent sea level rise exercise, which can be found here (https://serc.carleton.edu/NAGTWorkshops/gis/activities2/47971.html) . The simulation captures the evolution of sea level rise over the entire planet, taking into account eustatic sea level, sea level rise from perturbations to the gravity field, and sea level rise from local elastic rebound of the Earth's crust. 1. Simulations of Glacier Flow and Sensitivity to Climate Model the evolution of glaciers in Alaska, Patagonia and the Himalayan regions in response to variations in surface temperature, snow precipitation, and other factors related to climate change. Location Maps and Directions, Tel: 858-822-1413 They will then determine whether sea-level rise is occurring based on the data. This has been modified from Barbara Tewkbury's exercise available here: https://serc.carleton.edu/teachearth/activity_review.html, Used this activity? Based on work carried out by Dr. Gardner and Dr. Larour.Launch 1. Global sea level has changed throughout Earth's history. Published: Jul 30th, 2019; Recent housing growth rates are faster in high flood risk zones for most coastal states. Since the early 1990s, sea level has been measured from space using radar altimeters, which determine the height of the sea surface by m… Data collected from a series of satellite altimeters have measured a rise in global mean sea level (GMSL) of ∼3 ± 0.4 mm/year, resulting in more than 7 cm of total sea-level rise over the last 25 years. These two activities can be performed as a demonstration or in student groups. Already, he said, sea level rise and subsidence leave the road to the station frequently flooded at high tides. Ice already in the oceans does not contribute to sea level rise, but ice covering land will contribute to sea level rise upon melting. Haig GlacierUnderstand the evolution of Haig glacier… Show terms of use for text on this page », Show terms of use for media on this page », Joe Martin and Amanda Schmidt, Oberlin College, In this lab, modified from Barbara and David Tewksbury's. Warming temperatures cause mountain glaciers and polar ice caps to melt, thereby increasing the volume of water in the oceans. The researchers found one silver lining in their analyses: Curious as to whether past regulations on pollutants have had a significant effect on sea-level rise, the team focused on perhaps the most successful global remediation effort to date — the Montreal Protocol, an international treaty ratified by 197 countries in 1989, that effectively curbed emissions of ozone-depleting compounds worldwide. Regional, short-term sea level is constantly changing due to tidal and wind-driven effects on the ocean. Working with the style manager; table joins, raster reclassification; raster to polygon conversion; selection by location; working in the Python shell; reading ArcPy documentation; creating a Map Book with data driven map pages. Along the way, they learn about density, displacement, and climate change. The ISMIP6 project brings together an international group of glaciologists, atmospheric scientists and As a result, areas covered by sea ice don't absorb much solar energy, so temperatures in the polar regions remain relatively cool. Nationally, sea levels have risen 6.5 inches since 1950. Fiamma Straneo leads the Ocean Forcing group of ISMIP6, whose task is to forecast how the oceans around Greenland and Antarctica will change over the coming century, and how these changes interact with the edges of the ice sheets. Sea Level Rise; Ocean at the Door: New Homes and the Rising Sea. These estimates will feed directly into leading climate reports to shape future policy decisions. 4 are the expected changes due to thermal expansion of sea water alone, and do not include the effect of melted continental ice sheets. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in) on average. We use cookies to ensure that we give you the best experience on our website. This is then combined with TIGER census data to get estimates of the number of people affected by the change in shoreline. Columbia GlacierModel the evolution of Columbia glacier, Alaska.

At the same time, our oceans are getting warmer and expanding in volume as a result … Impact of sea level rise on sedimentary nitrogen removal processes in tidal freshwater ecosystem – Funded through NSF Grant Changes in land use and increasing population density have altered delivery rates and sources of N and OM to coastal. Sea level rise is increasing. Higher seas mean more water and more flooding during high tides, hurricanes, and rain storms. La Jolla, CA 92093-0202 In the first, you will look at recent trends in sea level from tidal gauge data going back to about 1940. The mass balance of the ice is not modeled, but forced by GRACE time series of ice thickness change in Greenland and Antarctica from 2003 to present-day. A scientific report endorsed by the United Nations states that unless greenhouse gas emissions are curtailed, average global temperatures may rise between one and. The discussion allows students to consider the connections between the experiment and sea level rise due to climate change. “Sea-Level Rise Data” worksheets for each student. Email: fstraneo@ucsd.edu, Fiamma Straneo leads the Ocean Forcing group of ISMIP6, whose task is to forecast how the oceans around Greenland and Antarctica will change over the coming century, and how these changes interact with the edges of the ice sheets. Standards are stated. More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017, which is a trend of roughly 30 cm (12 in) per century. If you continue to use this site we will assume that you are happy with it. The economic costs to US cities from flooding due to sea level rise and storm surge could amount to nearly $500 billion by 2050. Sea level rise is the result of two primary biophysical factors. A six-foot rise would put Atlantic City underwater. Material on this page is offered under a This exercise is used in an introductory GIS course for geology and environmental studies students. It is, however, meant to assess the sensitivity of local sea level rise to melting of polar regions. This activity was selected for the On the Cutting Edge Reviewed Teaching Collection, This activity has received positive reviews in a peer review process involving five review categories. With the effect of ice sheets included, the total rise could be larger by a substantial factor. Sea level rise: main consequences. As part of this effort, Donald Slater has led the development of.

In this lab, modified from Barbara and David Tewksbury's sea level rise lab, students use bathy/topo DEMs from NOAA to predict the location of shorelines after certain amounts of sea level rise and tsunami inundation. 13 million U.S. coastal residents are expected to be displaced by 2100 due to sea level rise. One of the scariest scenarios for near-term, disastrous sea-level rise may be off the table for now, according to a new study previewed at a recent scientific conference. Estimating ocean warming and sea level rise on regional to global scales; The role of the ocean in the Earth's climate system under global climate change; Projects. First, as the oceans absorb excess CO2 from the atmosphere, it causes ocean temperatures to rise which expands the volume of water in the ocean. The effects of sea level rise are global. In 2017, researchers led by the University of Melbourne, Australia predicted sea levels could rise as much as six feet by 2100. Sea level is measured by two main methods: tide gauges and satellite altimeters. The ISMIP6 project brings together an international group of glaciologists, atmospheric scientists and oceanographers to provide our best estimates to date of how much and how fast our ice sheets will shrink. Sea level rise is closely linked to increasing global temperatures. Students then display their results with data driven map … Scripps Institution of Oceanography The assessment questions require understanding other aspects of sea level rise that can be found in extension activity (What's Causing Sea Level Rise?
