The International Bathymetric Chart of the Arctic Ocean (IBCAO) Version 3.0
The International Bathymetric Chart of the Arctic Ocean (IBCAO) released its first gridded bathymetric compilation in 1999. The IBCAO bathymetric portrayals have since supported a wide range of Arctic science activities, for example, by providing constraint for ocean circulation models and the means to define and formulate hypotheses about the geologic origin of Arctic undersea features. IBCAO Version 3.0 represents the largest improvement since 1999 taking advantage of new data sets collected by the circum‐Arctic nations, opportunistic data collected from fishing vessels, data acquired from US Navy submarines and from research ships of various nations. Built using an improved gridding algorithm, this new grid is on a 500 meter spacing, revealing much greater details of the Arctic seafloor than IBCAO Version 1.0 (2.5 km) and Version 2.0 (2.0 km). The area covered by multibeam surveys has increased from ∼6% in Version 2.0 to ∼11% in Version 3.0. Key Points New gridded bathymetric portrayal of the Arctic Ocean Bathymetric crowd source data shows a new potential for the mapping community

Wireless ASPs reduce risks
A commentary states that mobile wireless communications is inherently complex, given that mobile workers must use multiple devices with various form factor and operating systems. Because of this, many mobile communications projects have never come to fruition. With the advent of the wireless application service provider model, in which businesses outsource some or all of their wireless application services, business risks are actually reduced. This accounts, in part, for the incredible growth in the overall ASP market - and the emerging wireless ASP market.

Tense and Aspect Inflections in Mexican Sign Language Verbs
Forty-nine videotaped clips of Mexican Sign Language (LSM), mostly narratives, were transcribed with glosses. The identified verbal signs were identified, and classified for further analysis. The videotaped subjects were two native signers (one with Deaf signing parents). The analysis led to the conclusion that LSM is an inflective language. A paradigm of nine verbal categories was identified: Present, Perfective Past, Perfective Future, Imperfective, Exhortative, Deontic, Assertive, Imperfective Non-Future and Imperfective Future. This dissertation focuses on the exhaustive description of the first four categories. A Cognitive Grammar (CG) approach (Langacker 1987a, 1991) was applied for the description of the semantic and morphosyntactic interactions of each inflection with three verbal Aktionsort subcategories: durative, punctual, and stative. Imperfective usages (e.g. habitual) and imaginary synchronizations (e.g. historical present) result from the Present form of durative verbs. Inchoative meanings emerge from the Perfective Past, or Perfective Future inflection of stative verbs, each with its corresponding temporal grounding. And the Imperfective inflection of durative verbs produces a progressive aspect. So far, no equivalent set of inflectionally induced aspectual nuances and tense categories has been reported for any other sign language.
