The deuterium excess of polar ice cores documents past changes in evaporation conditions and moisture origin. New data obtained from the European Project for Ice Coring in Antarctica Dome C East Antarctic ice core provide new insights on the sequence of events involved in Termination II, the transition between the penultimate glacial and interglacial periods. This termination is marked by a north-south seesaw behavior, with first a slow methane concentration rise associated with a strong Antarctic temperature warming and a slow deuterium excess rise. This first step is followed by an abrupt north Atlantic warming, an abrupt resumption of the East Asian summer monsoon, a sharp methane rise, and a CO2 overshoot, which coincide within dating uncertainties with the end of Antarctic optimum. Here, we show that this second phase is marked by a very sharp Dome C centennial deuterium excess rise, revealing abrupt reorganization of atmospheric circulation in the southern Indian Ocean sector.

STANDISH — Sacopee Valley pitcher Roderick Maynard notched eight strikeouts to lead the Hawks past George Stevens Academy in Saturday’s Class C state baseball championship at Saint Joseph’s College.Sacopee Valley (16-3) edged the GSA Eagles 3-2 for its first state title since 1993.“He’s an outstanding pitcher,” GSA coach Dan Kane said of Maynard. “Being a lefty, he made it a little bit tougher. He helped slow down the running game. More importantly, he didn’t allow a lot of guys on base.”Jacob Keenan started for GSA on the mound. The Hawks scored their first run in the bottom of the first. Brady Anderson singled on a line drive to centerfield, and Kyle Jordan followed with a blooper down the right field line to put runners on first and second. Maynard then singled to score Anderson and put Jordan on third. But GSA shortstop Taylor Schildroth ended Sacopee Valley’s scoring by bare-handing a chopper for the Eagles’ third out.This is placeholder textThis is placeholder textSacopee Valley added another run in the bottom of the third. Devin Day walked, and Dana Shea reached on a fielder’s choice that took out Day. GSA’s Marshal Lebel caught a popup in right field for the second out. But before the Eagles could notch a third, Jordan lined to left field for a double that scored Shea.The Hawks scored their third and final run in the fourth. Brandon Burnell led off with a double to deep left field, at which point Beckett Slayton replaced Keenan on the mound. A chopper to first advanced Burnell to third, and he scored on a throwing error to home for a 3-0 lead.“A lot of teams would fold, and we didn’t fold,” Kane said. “We got out there and competed and got after them, and we gave ourselves a chance.”GSA got on the board in the top of the fifth after Keenan singled to centerfield. Will Entwisle followed with a grounder to second, and he beat out the attempted double-play. With just one out, Stefan Simmons had the hit of the night for the Eagles with a triple to centerfield that scored Entwisle. But when Lebel couldn’t make contact in a suicide squeeze attempt, Simmons was tagged out running home. Lebel then struck out, putting a halt to GSA’s offensive momentum.The Eagles found it back in the next inning when Tyler McKenney reached second on a popup that landed between a cluster of three Sacopee players. A Tyler Snow sacrifice bunt advanced McKenney to third, and he reached home on a Schildroth groundout.“Most of the time, when you have a good pitcher like that and he’s got a two or three-run lead in the game, he doesn’t want to walk anybody,” Kane said of Maynard. “We finally started swinging on them — putting a good solid piece on them.”The Eagles held Sacopee Valley in the bottom of the sixth, but they couldn’t get rolling in the final inning. After Dakota Chipman struck out, Keenan singled and stole second. But Maynard would clinch the win with two more strikeouts. The game only lasted an hour and 10 minutes.GSA (18-2) hasn’t won a state championship since its back-to-back titles in 2004 and 2003. But, fortunately for the Eagles, the team is young. They only have two graduating seniors.“Two important ones,” Kane added, referring to Entwisle and Chipman. “But we’re getting ready for next year already.” Bio EHS names new boys’ soccer coach – July 13, 2016
