Average coseimic slip profiles

Kiran K.S. Thingbaijam, Russ J. Van Dissen, B. E. Shaw & Matt C. Gerstenberger
Despite the potential impact on earthquake rupture forecasts for seismic hazard analysis, derivation of applicable average coseismic slip profiles has received relatively limited attention. Here, we present improved insight using a set of rupture models of past earthquakes. We find that along-strike slip profiles are well approximated by a power-of-sine function with index = 1/2 (i.e. sinesqrt function), corroborating Biasi and Weldon (2006). However, elongated ruptures (with aspect ratios >5.0) have a flatter profile. Additionally,...

During IODP Expedition 382, two sites were drilled at 53.2°S at the northern edge of the Scotia Sea and three sites at 57.4°–59.4°S in the southern Scotia Sea within the Atlantic sector of the Southern Ocean. Sediments at both locations alternate between dominant terrigenous components during glacials and dominant biogenic components, carbonate at the northerly sites and opal in the southern Scotia Sea, during interglacials. Here we constrain the geochemical environment in interstitial waters using...

Authority, Identity and Ethics of Data Re-publication and Duplication

Lesley Wyborn , Kirsten Elger , Jens Klump , Kerstin Lehnert & Mingfang Wu
Today, research data is widely available in digital form, datasets are easily accessible online and the dataset creator should consider it advantageous as this leads to greater uptake. However, the downside is that digital datasets can be easily copied, duplicated in multiple places, and re-published through more than one repository or service. Particularly with web services, mirroring resources is a common practice, especially in online GIS packages and dashboards. ‘Copy WMS link’ buttons are common,...
