“Nitrous oxide is the world’s third largest greenhouse gas which, in high concentrations, can negatively affect both plant and animal health. It is released into the atmosphere by a process known as the Nitrogen Cycle. This is a natural process where nitrogen is reduced with hydrogen to yield ammonia, a form of nitrogen commonly used … Read more
Atmospheric Brown Clouds (ABCs) are composed of submicrometer aerosols, including black carbon and other constituents (e.g., sulfate, organics). Globally, ABCs are a major agent of climate change and long range pollution transport. Single particle mass spectra indicate ABC particles in size ranges that efficiently scatter (e.g., 0.2-1.0 μm) are comprised predominantly of internal mixtures that … Read more
As part of the New Jersey Meadowlands Commission GIS Outreach program, the MRRI-GIS department will be presenting the next phase of its Emergency Response Information System (ERIS) – a webMapping application that has been used by member municipalities in the Hackensack Meadowlands District since 2007. This presentation will highlight the new tools that will enhance … Read more
Studies in the District have found that the concentration of Lead (Pb) associated with small particles in the air (PM2.5) is high compared to suburban areas in New Jersey. In 2008, the EPA established stricter ambient air quality criteria for Lead based on total suspended particles (TSP) and not to exceed 0.15 µm/m3 (for rolling … Read more
The MRRI-GIS Department will be presenting a live demonstration of the newly released version of the popular Municipal Map and Emergency Response Information System (ERIS) to reporters interested in getting a first look at the available mapping tools for their constituent NJMC towns. This webMapping application will provide an effective tool for town officials in … Read more
Abstract: The New Jersey Meadowlands Commission has been monitoring ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2) and carbon dioxide (CO2) since 2007. These pollutants except CO2 are part of the principal pollutants that pose significant impact on human health established by USEPA. State of New Jersey and the federal government have … Read more
Abstract: Wetlands can potentially accumulate organic carbon at very high rate over long periods of time due to their continual accretion and burial of organic rich material into the sediment. Coupled with the anaerobic conditions of microbial activity where degradation happens at a very slow rate wetlands have an advantage over other environments due to … Read more
Abstract: The importance of using local ecotypes of species as building blocks in restored communities and the need of including information on genotypic differentiation has been stressed in restoration ecology. Large portions of brackish East Coast marshlands have been invaded by a non-native, European genotype of the common reed, Phragmites australis. As a result, only … Read more
NJMC COOP and GIS will present their latest program in collecting utility assests. This meeting will detail the efforts by the NJMC in collecting/organizing GIS data for muncipal officials to use in their day-to-day tasks.
Abstract: A transect of marsh cores from Jamaica Bay northward provides acrchives of vegetation history, climate change, and human impact. Community disturbaance of the forests and landscape is indicated by pollen and spore stratigraphy at time of European settlement up to present, with large losses of forest. Forests prior to European impact were comprised of … Read more
