Abstract: A time span of 15 years separated two surveys of the benthic macroinvertebrate community of the Hackensack Meadowlands. During each survey, three replicate grab samples were collected using a full-sized Ponar grab at 26 sampling locations during each season over a one year period. The original survey, conducted in 1987, recovered 65,565 organisms from … Read more
Abstract: The Hackensack Meadowlands region is an ideal setting for monitoring atmospheric air conditions. The preserved wetlands are surrounded by Routes 3 and 46 to the North and South, and Route 7 and Interstate 95 on the West and East. Since these wetlands are preserved, we know atmospheric pollutants must be caused by the automobiles … Read more
Abstract: Members of MRRI’s scientific research team presented their latest findings of the “New Jersey Turnpike Air Monitoring” study currently being conducted to the staff at the Environmental Protection Agency (EPA). The objective of the study is to determine how particulate concentration from Turnpike vehicle emissions is affected by seasons, day and night, traffic flow … Read more
Abstract: Dom Elefante and Alex Marti will present “Sewer and Stormwater Mapping: A Regional Approach to Municipal Information Sharing” at the 93rd Annual New Jersey Environment Association’s Conference in Atlantic City. The GIS Group’s role in providing a regional system in the development of a GIS infrastructure for utilities management within the 14 Meadowlands municipalities … Read more
Abstract: MRRI has been communicating spatially explicit data and information about the Hackensack Meadowlands District in northern New Jersey since 1992. A regional initiative to share GIS resources with and among local governments was approved under the Municipal Assistance Program. One component of the program was to develop the Emergency Reponse Information System (ERIS); a … Read more
Abstract: The Meadowlands Environmental Research Institute (MRRI) will be hosting students from Snyder High School’s AP Environmental Science class in Jersey City. Students will spend time interacting with MRRI staff and learning about our Analytical Lab, GIS Lab and Library. The trip will conclude with an educational walk along the nature trails that surround the … Read more
Abstract: Geophysical technologies are increasingly being used to non-invasively map and monitor the subsurface at spatiotemporal scales unobtainable with conventional, invasive methods of investigation. Geophysical research funded by the Meadowlands Environment Research Institute (MRRI) over the last five years has focused on applying geophysical technologies to the study of wetlands and monitoring subsurface processes in … Read more
Abstract: The New Jersey Meadowlands Commission has determined that remediation of the Kearny Marsh freshwater ecosystem is a high priority and has partnered with Rutgers University to achieve this goal. Human alterations affecting current hydrologic conditions include municipal stormwater inputs from the Town of Kearny, construction of railways and highways surrounding the marsh, creation of … Read more
Abstract: The Meadowlands Environment Center is teaming up with the MRRI lab to provide a hands-on learning experience for a GIS class from the Newark Science Park High School. They will come to the Meadowlands Environment Center for an all day field trip focused on the connections between sustainability and GIS. With the growing need … Read more
Abstract: Herons and Egrets that are seen feeding in the NJ Meadowlands mainly breed on islands in NY Habor and Long Island Sound. Their long-term population dynamics are complex, with dramatic fluctuations from year to year that imply large-scale ‘switching cascades’ — mass movement of individuals between locations from one breeding season to the next. … Read more
