Description: Rockweed is a brown algae found on rocky shores. The most common types of rockweed are within the genus Ascophyllum spp. and Fucus spp. (the latter is shown to the left). They grow slowly and can live from 3 to 15 years before breakage. Rockweeds have fronds that bear air bladders. These 'airbags' help the algae to stand up straight under water. Rockweed lacks true roots, stems, and leaves, and because they lack a vascular system, absorb dissolved nutrients directly through the blades. Rockweed attaches to rocks with a disc-like “holdfast”, and regenerate fronds from remaining holdfasts after a natural disturbance that removes upright fronds. [show more]
Description: Measles is an air-born infection caused by a paramyxovirus, mostly common in early childhood. In the present day, measles is considered an extinct disease in most parts of the world. According to WHO, in 1980, before widespread vaccination, measles caused an estimated 2.6 million deaths each year. However, in the recent years, the once eradicated disease started resurfacing in countries like New Zealand, Australia, and United States (CDC). It is one of the leading causes of death among young children even though a safe and cost-effective vaccine is available (WHO). [show more]
Description: The firestorm that erupted in San Diego County in the fall of 2007 devastated the area. This firestorm is considered to be the second most destructive fire in the history of the county, just after the Cedar Fire of 2003. High heat, low humidity, Santa Ana winds with gusts up to 100 mph, and other conditions provided optimal conditions for the wildfires to thrive.
Description: Pollinators such as wild bees and the Western honeybee, Apis mellifera, are important to humans and nature. Seventy-five percent of food crops and 90% of wild flowering plants benefit from animal pollinators (IPBES 2016).
Description: A collaborative public health project project, the All About Arsenic project was initiated in 2015 by researchers at Mount Desert Island Biological Laboratory (MDIBL) and Dartmouth College’s Toxic Metals Superfund Research Program.
Description: An estimated 73 million sharks were killed last year, primarily for their fins. Their populations are at critical levels, and they are still being fished out of the oceans at unsustainable rates. Some regional populations of shark species are down to 95 - 99%, which is considered functional extinction.
Description: This GIS story map introduces you to Denmark and the current climate politics in the country. We will then have a look at Denmark in a global context and finally, examine how GIS can help us when we are "Planning for climate change in Denmark".
Description: According to the University of Hawaii’s Honolulu Climate Change Commission, Oahu is the most at risk from sea-level rise compared to all other Hawaiian islands. By the middle of the century, a report assembled by the commission warned that regular high tide flooding with 3.2ft of local sea-level rise would put 18 miles of coastal road and 4000 settlements at risk (Westfall, 2018).
Description: The Adirondacks is a state park in Upstate New York that encompasses 6 million acres (larger than any National Park). The park contains a Forest Preserve that encompasses 2.6 million acres. The other 3.4 million acres are privately owned land that is regulated by the Adirondack Park Agency.
Description: Citi Bike is a bicycle sharing system established in 2013 in New York City. As of now, the nation’s largest bike-sharing system has 12,000 stations across Manhattan, Brooklyn, Queens, and Jersey City. Riding a bike is fun and healthy exercise. In urban areas like NYC, bike-sharing can also serve as a time-effective way of moving around tightly packed areas.
