Independent Digital Elevation Model of Greenland from GNSS-R data from TechDemoSat-1
No full textSGR-ReSI, TechDemoSat-1,Improved Digital Elevation Model (DEM) of the Greenland Ice Sheet derived from Global Navigation Satellite Systems-Reflectometry (GNSS-R). This builds on a previous study (Cartwright et al., 2018) using GNSS-R to derive an Antarctic DEM but uses improved processing and an additional 13 months of measurements. A median bias of under 10 m and root-mean-square (RMS) errors of under 166 m are obtained, as compared to existing DEMs. Funding was provided by NERC grant NE/L002531/1.,Gridded group delay altimetry from TechDemoSat-1's GNSS-R data collected between September 2014 and December 2018. For full details see Cartwright et al., 2020.,A median bias of under 10 m and root-mean-square (RMS) errors of under 166 m are obtained, as compared to existing DEMs.</span
Independent Digital Elevation Model of Antarctica from GNSS-R data from TechDemoSat-1 - VERSION 2.0

For full details see Cartwright et al., 2020.,Improved Digital Elevation Model (DEM) of the Antarctic Ice Sheet derived from Global Navigation Satellite Systems-Reflectometry (GNSS-R).

A median bias of under 10 m and root-mean-square (RMS) errors of under 53 m are obtained, as compared to existing DEMs. Funding was provided by NERC grant NE/L002531/1.,A median bias of under 10 m and root-mean-square (RMS) errors of under 53 m are obtained, as compared to existing DEMs. This represents, compared to the earlier study, a halving of the median bias to 9 m, an improvement in coverage of 18 %, and a four times higher spatial resolution (now gridded at 25 km). These are the first published satellite altimetry measurements of the region surrounding the South Pole. Comparisons south of 88° S yield RMS errors of less than 33 m when compared to NASA's Operation IceBridge measurements.</span

Dostine (MVM, T-22576). Paratypes. Northern Territory. 2 males (specimen CT-662 figured), 4 females (one figured), collected with holotype (MVM / MAGNT); 1 male, same site and collector, 19–20 May 2015; 4 males, 6 females, Leichhardt Springs, 19 May 2015, P.

The male of Ecnomina radonica sp. nov. is similar to those of E. thinotes Neboiss 1979 and E. volsellus Cartwright 1990 in possessing an elongate pair of simple dorsal processes on tergum X but can be distinguished from the latter two and all other species in the genus by the distinctive, slender and incurved, pincer-like inferior appendages. The wing venation of E. radonica sp. nov. (Fig. 1) differs from those figured for E. legula Neboiss 1977 and E. scutica Cartwright 2008 (Cartwright 2008, figs 3, 5), in that forewing forks 2, 3, and 4 and hind wing fork 3 are all relatively short. Description, male & female. Spurs: 3:4:4. Wings (slightly damaged) as in Fig. 1. Head, body, and wings light brown; wings similar to those of E. legula (Cartwright 2008, fig. 3) but most forks shorter. Length of each forewing: male 2.4–2.5 mm, female 2.8 mm. Forewing with forks 2, 3, 4, and 5 and discoidal cell; fork 2 relatively long, sessile, length of fork about 1.6–1.7 times length of fork 3; fork 3 relatively short, with long footstalk, fork about 1.7–1.8 times length footstalk, crossveins r-m and m nearly contiguous at fork 3, fork 4 about 0.8 times length of fork 3; fork 5 long, length about 1.9–2.0 times length of fork 4. Hind wing with forks 2, 3, and 5 and discoidal cell; fork 2 with short footstalk, length of fork 2 about 2.0–2.3 times length of fork 3; fork 3 shorter than its footstalk. Male. Tergum X with one pair of relatively slender dorsal processes (Figs 2, 4), in dorsal view robust in basal third (Fig. 4). Superior appendages slender, somewhat rod-like (Figs 2, 4), in lateral view with length about 6.8 times width (Fig. 2); in dorsal view with length about 5.5 times width, each with single, robust subapical spine (Fig. 4). Phallus simple, tube-like (Figs 2, 3, 4). Inferior appendages slender, curved strongly downward and mesad like pincers, fused at base (Figs 2, 3). Female. Genitalia with a single slender, elongate mesal process on sternite VIII; segment IX relatively long and slender, segment X relatively short and slender in ventral view (Fig. 5). Etymology. Radonica —from the type locality (Radon Springs). Remarks. Ten male specimens of Ecnomina radonica are recorded from three localities within Kakadu NP, NT (latitude range 12.75– 12.83°S).Published as part of Cartwright, David I. & Dostine, Peter, 2022, Five new species and new records of caddisflies (Insecta: Trichoptera) from Australia's ' Top End', pp. 283-304 in Zootaxa 5138 (3) on pages 287-288, DOI: 10.11646/zootaxa.5138.3.4, http://zenodo.org/record/655973

No full textEcnomina gippslandica sp. nov. Figs 162–164, 193 Diagnosis. Ecnomina gippslandica most closely resembles E. serrata and E. sheldoni from which it is distinguished because the superior appendages are not tapered in distal half and also have a small excision apically. Description. Head, body and wings brown; wings similar to E. merki (Fig. 172). Forewing length about 2.9–3.2 times width: male 3.3–3.6 mm, female 3.8 mm. Forewing fork 2 relatively long, sessile, length about 1.4–1.5 times length of fork 3; fork 3 relatively short, with long footstalk, length fork about 2.5–4.6 times length footstalk, footstalk length about 1.2–1.6 times length cross-vein m, r-m and m nearly contiguous at footstalk fork 3, r-m and m separated by about 0.4–0.8 times length of cross-vein m; fork 4 slightly shorter than fork 3; fork 5 long, length about twice length of fork 4. Hindwing length about 3.3 times width, fork 2 sessile, length about 1.6–1.7 times length of fork 3.
