Test edit
Alpinacris crassicauda is a species of grasshopper only known from West Coast Region and Tasman Region, New Zealand. A. crassicauda was described in 1967 by Robert Sidney Bigelow,[1] with a type locality of Lead Hills, Boulder Lake (45°19′22″S 169°12′27″E / 45.322814°S 169.207411°E). A male holotype and paratype are deposited in the Canterbury Museum, Christchurch.

Boats edit
The Balcongerät was standard on the Type XXI and the Type XXIII nonetheless was also fitted to several Type VIIC’s and Type IX’s and one Type X.
- Five known Type VIIC/41 U-boats with a Balcongerät were U-995, U-997, U-1021, U-1105 and U-1308.
- Five known Type IX’s U-boats with a Balcongerät were U-534, U-805, U-858, U-873 and U-889.
- One known Type X, U-boat with a Balcongerät was U-234
A new design of GHG had been asked for by the Oberkommando der Marine, a new system was required to reduce noise interference and to have a greater detection range[2]. In February 1943, the first Balcony hydrophones was successfully tested on U-194 a Type IXC/40[3]. The Balcongerät was integrated into a hull casting and placed in front of the keel. It consisted of 48 hydrophones compare to 24 on the older GHG's[3]. With its lower position on the hull casting and its hydrodynamics shape, it made it less vulnerable to many sorts of hampering interference[3]. From photographs of U-995 Balcongerät, other attempts can be seen to reduce the noise interference, from outside the U-boat. No exterior riveting can be seen, the outer shell of the Balcongerät was likely welded to the internal framing and then the welds on the surface grinded smooth. Also no fixing points can be seen on the cover plate for the hydrophones so it is expected that they used countersunk screws to secure the cover plate to the Balcongerät. The Balcongerät give a far better detection range than either the older GHG or KDB systems[4]. The detection range was increase approximately 70%, compared to older GHG hydrophones system and with improved electronics, enabled more accurate reading[3][5].
