MBRP – Genetics, Remote Sensing, and Mycofoam

The Marine Biology Research Program has started 2014 with spunk. A select group of 10th grade marine research scholars are currently working on a project comparing the genetic differences between three eastern oyster groups – Muscungus Bay, Fishers Island, and wild type oysters from Soundview Park, Bronx. The importance of this project is to determine genetic similarities or differences caused by years of selective breeding. This project may also inform restoration efforts of the types of oysters that may best adapt to the Hudson River Estuary. Our 11th grade scholars are learning to configure and calibrate a professional water quality remote sensor to measure chlorophyll – an important environmental variable for oyster restoration. Lastly, a team of 10th and 11th grade scholars met last week with Ecovative scientist Sue Van Hook to brainstorm how to replace the use of Styrofoam with biodegradable foams made of fungus. Aside from these great projects, our young research scholars have been hard at work in our marine science lab to get the re-circulating systems up and running. We expect to have many exciting projects for this year’s Science Symposium in May. Thanks to Sam Janis from the Harbor Foundation, Pablo Garcia, long time field staff of the NY Harbor School, Pete Malinowski, NY Harbor School’s aquaculture teacher, and the Urban Barcode Project folks for their support.

Marine Research Class of ’14 Highlight

Marine Research students monitor water quality indicators in the HRE weekly

Intermediate Marine Biology Research (MBRP) students monitor the Upper Hudson River Estuary (HRE) on Governors Island. With water quality gear in hand the students set out to monitor the waters on a weekly basis to determine the state of health of the HRE in the heart of NYC. The students replicate their sampling and collect their data on data sheets. They then process the information in the lab and work towards completing a college level research paper which they will submit at the end of the year to the NYC Science and Engineering fair in order to compete for scholarships and prizes. Some of the projects involve monitoring physical-chemical water parameters, zooplankton, and fish. This kind of experiential learning helps them to develop critical thinking skills and prepares them for college and industry while keeping it real. For more images of their work click here.

Day 02 – Harbor SEALs HRE Monitoring

The Harbor SEALs completed their 2nd day of monitoring of the Upper Hudson River Estuary. Team work was in full display as the SEALs worked in subfreezing temperature. The data is available for the public here. Once the samples are taken, students quickly measure the dissolved oxygen using the Azide modification of the Winkler method, measure temperature, and enterococcus bacteria. It is quite a scene to watch the level of intensity the students obtain on a given sampling day. For more images of the SEALs at work click here.

On another note, congratulations to the winners of the invertebrate larvae identification contest. 10th graders Tahirah and Nicolle successfully identified the nauplius larvae as pertaining to a barnacle.

Day 01 – Harbor SEALs Monitoring Kick-Off + More

Last Wednesday, New York Harbor School’s Harbor SEALs kicked off their first day of full scale monitoring for the Hudson River Estuary  Water/Air Quality Monitoring Program. We had  a total of 21 volunteers working the jam packed schedule. In all, 4 different localities were sampled at exactly the same time in order to compare water conditions and determine the influence of the currents from the different bodies of water flowing through the Battery. We thank all the volunteers – adults and children who participated. We also thank the EPA for its support of this important project. We are in the process of developing a page on this site to post the data.

Additionally, last week our 11th grade Marine Biology Research students found a nauplius larva during their weekly sampling run at Pier 101. With a water temperature of 4 C and winter in full force, we were surprised to see that the Harbor is preparing for an early spring. Can you identify what Infraclass of organisms it belongs to? E-mail your answer to mgonzalez@harborseals.org. The first correct answer will win a prize (high school students only, sorry;).

Harbor SEALs Citizen Scientists Train to Monitor the Hudson River Estuary

Whether at night in freezing temperature or by day, the Harbor SEALs get their water quality data. Entrusted by the EPA to monitor the dissolved oxygen, bacteria, and nutrients in the water, these Volunteer Citizen Scientists are adding pieces to the environmental puzzle surrounding Governors Island and the Upper Hudson River Estuary. With the data they’re collecting, the SEALs will provide answers to the following questions: 01) do the waters of the East River cross over to the west side of Governors Island, 02) do the waters of the Hudson cross over to the east side of Governors Island, and 03) is there a difference in the nutrient and bacteria load between the east and west sides of Governors Island and Lower Manhattan? These questions are important if we are to look for ideal localities in which to re-populate oysters and other species. Stay tuned for more Harbor SEALs updates in the coming months.

Aquatic Ecosystem Models – Class of ’15

Orlando, Alisha, and Averille working on their Aquatic Ecosystem Models.

So far this year the 10th grade Marine Biology Research students have done a great job of working together to produce exceptional results. Putting together Aquatic Ecosystem Models, they’ve begun to learn the basics of water chemistry, physics, and ecology. From jump starting the nitrification cycle in their Models by adding ammonium chloride and nitrifying bacteria to adding terrestrial plants for nitrate removal, these future environmental scientists are learning what it takes to keep an ecosystem healthy from the bottom up. Once these students have mastered keeping their Ecosystems healthy they’ll start formulating projects around the Hudson River Estuary to apply their skills to the real world. Continue here.
