the mainland of Antarctica. In winter there is darkness for 105 days - darkness relieved by magnificent auroral displays. The relief of Halley is a major undertaking with supplies being landed twice a year by ship onto the ice shelf and then towed on sledges by Sno-cats to Halley, some 12 km distant from the ice edge.</abstractText>953 </abstract>954 <descriptionSection>955 <dgDescriptionText>Halley V is the fifth station to be built on the Brunt Ice Shelf. The first was established for the International Geophysical Year (IGY) in 1957-58, and named after the astronomer Edmond Halley. It filled an important gap in the IGY Antarctic network with studies in meteorology, glaciology, seismology, radio astronomy, and geospace science. Many of these studies have continued uninterrupted since then.956 <P>957 Studies at Halley are crucial for a global perspective on ozone depletion, atmospheric pollution, sea level rise and climate change. Ozone has been measured at Halley since 1956. A spring-time depletion in stratospheric ozone was discovered by BAS in 1985, and this led very quickly to the international response to curtail production of CFCs.958 <P>959 Halley, lying within the auroral zone, is ideally situated for geospace research. An HF (SHARE) radar, supported by a suite of other powerful radio and optical instruments including remote unmanned Automatic Geophysical Observatories, provides an unparalleled spatial picture of the consequences of geospace interactions in the upper atmosphere over an area of around three million square km above the South Pole.960 <P>961 Halley V contains a mix of building technologies. Three buildings are located on platforms on steel legs, which are jacked up annually to keep them clear of the accumulated snowfall. An accommodation building and a garage weighing over 50 tons are mounted on skis and towed each year to a new position. Halley I to Halley IV were built directly on the snow and were each abandoned within ten years, having been crushed by the overlying ice.962 <P>963 The station operates throughout the year with a maximum population of 65 in the summer and an average of 15 over winter. The Emperor penguin colony near Halley, which is present from May to February, is a special attraction, while other recreational trips take members further inland towards the "hinge zone" where the floating ice shelf is joined to the continent.</dgDescriptionText>964 <contentType>text/plain</contentType>965 </descriptionSection>966 <descriptionSection>967 <descriptionOnlineReference>968 <dgSimpleLink>969 <name>URI</name>970 <URI>www.antarctica.ac.uk/Living_and_Working/Stations/Halley/index.php</URI>971 </dgSimpleLink>972 </descriptionOnlineReference>973 </descriptionSection>974 </dgMetadataDescription>975 1043 <name>Halley Bay, Antarctica</name> 976 1044 <abbreviation/> 977 <dgObservationStation> 978 <contactDetails> 979 <fax>unknown</fax> 980 <telephone>unknown</telephone> 981 <address> 982 <addressline>unknown</addressline> 983 <city>unknown</city> 984 <postcode>unknown</postcode> 985 <country>unknown</country> 986 </address> 987 <URI>unknown</URI> 988 </contactDetails> 989 <dgStationaryPlatform> 990 <position> 991 <positionLatitude>0</positionLatitude> 992 <positionLongitude>0</positionLongitude> 993 </position> 994 </dgStationaryPlatform> 995 </dgObservationStation> 1045 <dgObservationStation/> 996 1046 </observationstation> 997 1047 </RelatedDeployment> … … 1005 1055 </dgMetadataID> 1006 1056 <activity> 1007 <error>not found</error> 1008 <repositoryIdentifier>badc.nerc.ac.uk</repositoryIdentifier> 1009 <localIdentifier>dataent_activity_chablis</localIdentifier> 1057 <dgMetadataID> 1058 <schemeIdentifier>NDG-B0</schemeIdentifier> 1059 <repositoryIdentifier>badc.nerc.ac.uk</repositoryIdentifier> 1060 <localIdentifier>activity_activity_chablis</localIdentifier> 1061 </dgMetadataID> 1062 <name>Chemistry of the Antarctic Boundary Layer and the Interface with Snow</name> 1063 <abbreviation>chablis</abbreviation> 1064 <dgActivity/> 1010 1065 </activity> 1011 1066 <dataproductiontool> … … 1015 1070 <localIdentifier>dpt_11721944072615528</localIdentifier> 1016 1071 </dgMetadataID> 1017 <dgMetadataDescription>1018 <metadataDescriptionID>1019 <schemeIdentifier>NDG-B0</schemeIdentifier>1020 <repositoryIdentifier>badc.nerc.ac.uk</repositoryIdentifier>1021 <localIdentifier>metdesc_11721944072615529</localIdentifier>1022 </metadataDescriptionID>1023 <metadataDescriptionLastUpdated>2007-02-23</metadataDescriptionLastUpdated>1024 <abstract>1025 <abstractText/>1026 </abstract>1027 <descriptionSection>1028 <dgDescriptionText/>1029 <contentType>text/plain</contentType>1030 </descriptionSection>1031 <descriptionSection>1032 <descriptionOnlineReference>1033 <dgSimpleLink>1034 <name>URI</name>1035 <URI/>1036 </dgSimpleLink>1037 </descriptionOnlineReference>1038 </descriptionSection>1039 </dgMetadataDescription>1040 1072 <name>UEA: Cryo-PAN</name> 1041 1073 <abbreviation>uea-cryo-pan</abbreviation> 1042 <dgDataProductionTool> 1043 <dgInstrument/> 1044 </dgDataProductionTool> 1074 <dgDataProductionTool/> 1045 1075 </dataproductiontool> 1046 1076 <observationstation> … … 1050 1080 <localIdentifier>obs_1162914786499342</localIdentifier> 1051 1081 </dgMetadataID> 1052 <dgMetadataDescription>1053 <metadataDescriptionID>1054 <schemeIdentifier>NDG-B0</schemeIdentifier>1055 <repositoryIdentifier>badc.nerc.ac.uk</repositoryIdentifier>1056 <localIdentifier>metdesc_116291478659343</localIdentifier>1057 </metadataDescriptionID>1058 <metadataDescriptionLastUpdated>2006-11-07</metadataDescriptionLastUpdated>1059 <abstract>1060 <abstractText>Halley is the UK's most isolated station (75.35S, 26.39W) and is afloat on an ice shelf on the mainland of Antarctica.

The first was established for the International Geophysical Year (IGY) in 1957-58, and named after the astronomer Edmond Halley. It filled an important gap in the IGY Antarctic network with studies in meteorology, glaciology, seismology, radio astronomy, and geospace science. Many of these studies have continued uninterrupted since then.2468 <P>2469 Studies at Halley are crucial for a global perspective on ozone depletion, atmospheric pollution, sea level rise and climate change. Ozone has been measured at Halley since 1956. A spring-time depletion in stratospheric ozone was discovered by BAS in 1985, and this led very quickly to the international response to curtail production of CFCs.2470 <P>2471 Halley, lying within the auroral zone, is ideally situated for geospace research. An HF (SHARE) radar, supported by a suite of other powerful radio and optical instruments including remote unmanned Automatic Geophysical Observatories, provides an unparalleled spatial picture of the consequences of geospace interactions in the upper atmosphere over an area of around three million square km above the South Pole.2472 <P>2473 Halley V contains a mix of building technologies. Three buildings are located on platforms on steel legs, which are jacked up annually to keep them clear of the accumulated snowfall.
