Limnology and Oceanography: Methods, EarlyView.Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Sediment trap preservative choice impacts particle‐associated microbial community composition
Limnology and Oceanography: Methods, EarlyView.Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

A Polar Rover for Large-Scale Scientific Surveys: Design, Implementation and Field Test Results
International Journal of Advanced Robotic Systems, 2015 Exploration of polar regions is of great importance to scientific research. Unfortunately, due to the harsh environment, most of the regions on the Antarctic continent are still unreachable for humankind.

A quasi-Lagrangian coordinate system based on high resolution tracer observations: implementation for the Antarctic polar vortex [PDF]
, 2008 In order to quantitatively analyse the chemical and dynamical evolution of the polar vortex it has proven extremely useful to work with coordinate systems that follow the vortex flow.

Lack of an HSP70 heat shock response in two Antarctic marine invertebrates [PDF]
, 2008 Members of the HSP70 gene family comprising the inducible (HSP70) genes and GRP78 (glucose-regulated protein 78 kDa) were identified in an Antarctic sea star (Odontaster validus) and an Antarctic gammarid (Paraceradocus gibber). These genes were surveyed
