Analysis of acoustic dot echo signature over an Antarctic ice shelf: the possible remote sensing of Antarctic petrels

first_imgData from a monostatic acoustic radar operating at British Antarctic Survey’s Halley station on a coastal Antarctic ice shelf show a band of small target echoes at an altitude of 700-1000 m during spring 1991. Statistical analysis of the echo signature show that the targets are spread more evenly in the horizontal than would be expected for a random signature, whilst the local distribution in the vertical is Gaussian. Similar echo signatures have been observed previously, and are attributed to birds, bats or insects: the Antarctic data are also consistent with bird targets, but the case is not proven. No birds have been observed directly, but at 700 in they would be barely visible to the naked eye. The nearest nesting area with suitably large numbers of birds (Antarctic petrels, Thalassoica antarctica) is a few hundred kilometres away. Estimates of velocity and target density imply that the Halley site would need to be specially favoured by the colony for their acoustic signature to be observed in such numbers, but such might be the case due to the presence of perennial coastal open water to the west of the station.last_img read more

PREMIUMMass-scale farming on peatland detrimental to environment, experts warn

first_imgPresident Joko “Jokowi” Widiodo has recently ordered state-owned companies (BUMN) to make swathes of peatland in Kalimantan available for rice fields to anticipate possible food shortages during the COVID-19 pandemic.The government has yet to work out the details, but the Agriculture Ministry is considering making available 600,000 hectares of peatland in Central Kalimantan to produce buffer stocks.Another 300,000 ha plot of peatland has been set aside for the project in the province, Coordinating Economic Minister Airlangga Hartanto said.But the plan has met with doubt from experts and farmers, who said past experience had shown that such a mass-scale project was detrimental to the environment and only small-scale farming on peatland was viable.Bogor Agricultural University (IPB) researcher Dwi Andreas Santosa noted a project to turn 1 million ha of peatland … Linkedin Forgot Password ? peatland #Peatland farming #environment environment Kalimantan #CentralKalimantan Facebook Google Topics : Log in with your social account LOG INDon’t have an account?

NPFL…NPFL…NPFL… Wikki Piles Pressure on Flying Antelopes

first_imgWikki Tourists yesterday moved into second place on the Nigerian Professional Football League (NPFL) table after a 3-0 spanking of bottom team Ikorodu United in Bauchi.Wikki now have 31 points, same as Rivers United, but enjoy a superior goals difference.The Bauchi club is just a point behind leaders Rangers, pending the final determination of the expulsion of Giwa FC from the league.The leading scorer in the league Godwin Obaje did not score for Wikki yesterday, but Saidu Abdullahi got a brace with Hamza Tiya also on target for the home team.There were also home wins for Warri Wolves and Lobi Stars.Wolves beat El Kanemi 3-1, while 10-man Lobi pipped Rivers United 1-0.Lobi defender Solomon Kwambe was sent off after his second booking and Rivers United had the chance to draw level at the stroke of full time but Chinonso Okonkwo blasted wide his penalty.Meanwhile, Rivers United coach, Stanley Eguma, has warned that it is too early in the campaign to start talking of his club winning the Nigeria league crown.Rivers United failed to go top of the table after the loss to Lobi as the league reaches the halfway mark.However, experienced coach Eguma insisted the journey to the championship is still a long way off.“Talking about us winning the title at this stage of the season is an insult to all the other teams in the league,” he maintained.“It is still too early to start talking about such things because we have not even got to the half way stage of the season.“There are still so many games to be played, but our objectives are clear to us.“We will continue working hard and taking things one game at a time.”Eguma is still without first choice defenders, Yaovi Douhadji and Chigozie Ihunda, while Ghanaian marksman Godbless Asamoah, who suffered a hamstring strain in midweek, did not travel to Makurdi.Ivorian star Guy Kuemian however made a welcome return to first-team action when he played for the first time since April 10 in Wednesday’s 1-0 win over Akwa United in Port Harcourt.Eguma also said his side was the underdogs in yesterday’s match in Makurdi.Rivers United has won four of their last six games.MATCH DAY 19Plateau Utd 0-0 PillarsLobi 1-0 Rivers UtdWikki 3-0 IkoroduAkwa Utd 2-0 3SCWolves 3-1 El KanemiAbia War’ 1-2  SunshineShare this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegramlast_img read more
