This is particularly the case if samples are collected by non-conventional techniques such as those required for aquatic subglacial environments. In this paper we present the first analysis of a subglacial brine from Taylor Valley, (~ 78°S), Antarctica for the trace metals: Ba, Co, Mo, Rb, Sr, V, and U. Samples were collected englacially using an electrothermal melting probe called the IceMole. This probe uses differential heating of a copper head as well as the probe's sidewalls and an ice screw at the melting head to move through glacier ice. Detailed blanks, meltwater, and subglacial brine samples were collected to evaluate the impact of the IceMole and the borehole pump, the melting and collection process, filtration, and storage on the geochemistry of the samples collected by this device. Comparisons between melt water profiles through the glacier ice and blank analysis, with published studies on ice geochemistry, suggest the potential for minor contributions of some species Rb, As, Co, Mn, Ni, NH4+, and NO2-+NO3- from the IceMole. The ability to conduct detailed chemical analyses of subglacial fluids collected with melting probes is critical for the future exploration of the hundreds of deep subglacial lakes in Antarctica.}, language = {en} } @article{GerhardtWacker1999, author = {Gerhardt, Hans Joachim and Wacker, J.}, title = {Immissionsprognosen auf der Basis von Windkanaluntersuchungen}, series = {Immissionsschutz. 4 (1999), H. 3}, journal = {Immissionsschutz. 4 (1999), H. 3}, isbn = {1430-9262}, pages = {84 -- 89}, year = {1999}, language = {de} } @article{GerhardtSchoenwaldKonrath2007, author = {Gerhardt, Hans Joachim and Sch{\"o}nwald, J. and Konrath, B.}, title = {Verwendung von Leichtgas bei Brandsimulationen - unzul{\"a}ssig oder sinnvoll?}, series = {VFDB-Zeitschrift : Forschung, Technik und Management im Brandschutz. 56 (2007), H. 1}, journal = {VFDB-Zeitschrift : Forschung, Technik und Management im Brandschutz. 56 (2007), H. 1}, isbn = {0042-1804}, pages = {29 -- 31}, year = {2007}, language = {de} } @article{GerhardtSchoenwaldForssmannetal.2005, author = {Gerhardt, Hans Joachim and Sch{\"o}nwald, J. and Forßmann, R. and Große, Wolfgang}, title = {Modulation der Windenergie durch optimierte Uferbepflanzung zur Steuerung der Oberfl{\"a}chenstr{\"o}mung f{\"u}r das Entfernung von Treibgut}, series = {Der F{\"u}hlinger See : Beitr{\"a}ge zur Erhaltung der {\"o}kologischen Qualit{\"a}t / hrsg. von Wolfgang Große ... - ({\"O}kologie und nachhaltige Entwicklung von Sport- und Freizeitseen ; 1)}, journal = {Der F{\"u}hlinger See : Beitr{\"a}ge zur Erhaltung der {\"o}kologischen Qualit{\"a}t / hrsg. von Wolfgang Große ... - ({\"O}kologie und nachhaltige Entwicklung von Sport- und Freizeitseen ; 1)}, publisher = {Monsenstein und Vannerdat}, address = {M{\"u}nster}, isbn = {3-86582-212-6}, pages = {95 -- 108}, year = {2005}, language = {de} } @article{GerhardtSchoenwald2002, author = {Gerhardt, Hans Joachim and Sch{\"o}nwald, J.}, title = {Eine neue Brandsimulationsvorrichtung}, series = {vfdb-Zeitschrift. 51 (2002), H. 3}, journal = {vfdb-Zeitschrift. 51 (2002), H. 3}, isbn = {0042-1804}, pages = {91 -- 93}, year = {2002}, language = {de} } @article{GerhardtSchwarz2003, author = {Gerhardt, Hans Joachim and Schwarz, N.}, title = {Entrauchung {\"u}ber Seitenw{\"a}nde}, series = {vfdb-Zeitschrift. 52 (2003), H. 1}, journal = {vfdb-Zeitschrift. 52 (2003), H. 1}, isbn = {0042-1804}, pages = {25 -- 35}, year = {2003}, language = {de} } @article{GerhardtSchmidtJung2002, author = {Gerhardt, Hans Joachim and Schmidt, G. and Jung, G.}, title = {Rauchversuch in einem Hochregallager}, series = {Bautechnik. 79 (2002), H. 6}, journal = {Bautechnik. 79 (2002), H. 6}, isbn = {0932-8351}, pages = {414 -- 417}, year = {2002}, language = {de} } @article{GerhardtRudolph2000, author = {Gerhardt, Hans Joachim and Rudolph, M.}, title = {Steuerungsstrategien f{\"u}r Fensterbet{\"a}tigungen von Hochh{\"a}usern.
