Weather Alert  

AIR QUALITY ALERT IN EFFECT FROM MIDNIGHT TONIGHT TO MIDNIGHT EDT THURSDAY NIGHT The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for the following counties: New York, Bronx, Kings, Queens, Richmond, Nassau, Suffolk, Westchester, Rockland, Orange, Putnam. from midnight tonight to midnight EDT Thursday night. Air quality levels in outdoor air are predicted to be greater than an Air Quality Index value of 100 for the pollutant of Fine Particulates. The Air Quality Index, or AQI, was created as an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern. When pollution levels are elevated, the New York State Department of Health recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, and those with preexisting respiratory problems such as asthma or heart disease. Those with symptoms should consider consulting their personal physician. A toll free air quality hotline has been established so New York residents can stay informed on the air quality situation. The toll free number is 1 800 5 3 5, 1 3 4 5.

Sugar kelp is good for the environment. Much like oysters, it filters nitrogen and CO2 from the water, helping to reduce the harmful algae blooms and improve the overall chemistry of harbors and bays. Sugar kelp - also known as the Devils’ apron - also has nutritional value and is considered a superfood by many.

 

This underwater plant is, according to a NOAA website description, “a yellowish brown marine algae wildly cultivated and eaten in Asia and growing in popularity in the United States as a nutritious food high in fiber, vitamins, and minerals.” It has also long been used as a sweetener and is often used in food and cosmetics as a thickening and gelling agent.

 

In December 2020, Setauket Harbor Task Force (SHTF), a non-profit environmental association that promotes clean water and resilient harbors, with the assistance of the Town of Brookhaven Bay Constables, dropped mooring anchors and set up the kelp growing field’s area in Setauket Harbor, according to a press release from Brookhaven Town. In January 2021, they attached the kelp seedlings to 100-foot lines just under the surface of the water between buoys in Setauket Harbor.

According SHFT, the program's goal is to promote sustainable aquaculture in local harbors and bays and also to clean up the water by removing excess nitrogen and CO2 from the water. 

 

This May, Brookhaven Town Supervisor Ed Romaine and Town Councilmember Jonathan Kornreich were at Port Jefferson Harbor during the harvest of Sugar Kelp with members of SHTF, including Trustee George Hoffman (left) and Chairwoman Laurie Vetere.

SHTF and Brookhaven Town Bay constables harvested over 200 lbs. of sugar kelp which was placed in mesh bags and weighed. It was then sent to Stony Brook University marine sciences labs for analysis.
