Google Maps: Length Of Day In New York State On the First Day of Autumn

The first day of autumn does not have exactly 12 hours day and 12 hours of night. There is about 12 hours and 7 minutes of daylight, depending on what part of New York State you are to celebrate the autumn equinox due to refraction of light on the earth's atmosphere. This is The Town of Massena will have the longest day in all of New York State, at 12 hours, 7 minutes and 54 seconds. The Borough of Staten Island will have shortest day, at 12 hours, 7 minutes and 29 seconds. On Wednesday, September 27th this reverses -- the day will actually be slightly longer in Staten Island then Massena.

End-of-Summer Arctic Sea Ice Extent Is Eighth Lowest on Record

"Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite data by NSIDC and NASA showed that at 1.79 million square miles (4.64 million square kilometers), this year’s Arctic sea ice minimum extent is the eighth lowest in the consistent long-term satellite record, which began in 1978."

"Arctic sea ice appears to have reached a record low wintertime maximum extent for 2017, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. Observations indicate that on Sept. 13, 2017 ice extent shrunk to the eighth lowest in the satellite record, at 4.64 million square miles, or 1.79 million square miles."

"Arctic sea ice, the layer of frozen seawater covering much of the Arctic Ocean and neighboring seas, is often referred to as the planet’s air conditioner: its white surface bounces solar energy back to space, cooling the globe. The sea ice cap changes with the season, growing in the autumn and winter and shrinking in the spring and summer. Its minimum summertime extent, which typically occurs in September, has been decreasing, overall, at a rapid pace since the late 1970s due to warming temperatures."

Google Maps: Wildlife Management Units (WMUs)

Wildlife Management Units (WMUs) are the geographical units DEC uses to set hunting and trapping seasons in New York State. This map is similar to the online one on the DEC website, however I added random colors to make the different WMUs stand out better.

Updated 9/19/17 with the Northern Southern Zone line, shown in red. You may need to zoom in to see the Northern-Southern Line clearly.

Map: Bear Swamp State Forest

Map: Bear Swamp State Forest

Bear Swamp State Forest is covers 3,316 acres in Cayuga County in the Finger Lakes State Forest. This should not be confused with the similarly named state forest in Otsego County.

The forest is known for its nordic ski trail, and its large wetland and creek that bisect the forest. The ski trail system, over 13 miles in length, was developed with volunteer help in the 1980's. The trail has become increasingly popular, and was improved in 1993 by DEC. There is also a long multiple use trail on the forest here on can mountain bike, hike, snowmbile or horseback ride. Parts of this trail are accessbile for those with mobility issues.
