Origin of High Density Seabed Pockmark Fields and Their Use in Inferring Bottom Currents
Geosciences, 2018 Some of the highest density pockmark fields in the world have been observed on the northwest Australian continental shelf (>700/km2) where they occur in muddy, organic-rich sediment around carbonate banks and paleochannels.

Short-term effects of CO₂-induced low pH exposure on target gene expression in Platynereis dumerilii [PDF]
, 2016 Objective: Increasing atmospheric CO₂ concentration are causing changes to the seawater carbonate chemistry, lowering the pH and we study potential impacts of these changes at the molecular level in a non-calcifying, marine polychaete species Platynereis

Use of isotope dilution method to predict bioavailability of organic pollutants in historically contaminated sediments. [PDF]
, 2014 Many cases of severe environmental contamination arise from historical episodes, where recalcitrant contaminants have resided in the environment for a prolonged time, leading to potentially decreased bioavailability.

Final report : benthic samples taken from the Padre Island National Seashore [PDF]
, 1992 From March 1989 through January 1992 sediment samples were taken from subtidal areas within the boundary of the Padre Island National Seashore. These samples were taken as part of a large multidisciplinary study to determine how a hot, hypersaline ...

Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Effects of low seawater pH on the marine polychaete Platynereis dumerilii [PDF]
, 2015 An important priority for any organism is to maintain internal cellular homeostasis including acidbase balance. Yet, the molecular level impacts of changing environmental conditions, such as low pH, remain uncharacterised.

The impacts of biological invasions
Biological Reviews, EarlyView.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
, 2013 In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.
