Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Chemie Ingenieur Technik, EarlyView.Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Studies of seafloor geomorphology across various spatial scales in Antarctica [PDF]
, 2016 At Geoscience Australia, we use bathymetry data and seafloor geomorphology information across a range of spatial scales. I will present examples of where this information has been applied to continental, regional and local-scale studies in Antarctica ...

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Using multibeam echoes in seafloor characterisation and classification [PDF]
, 2008 The method of seabed identification and classification from multibeam sonar echoes is presented. The proposed approach is based on calculation of a set of parameters of an echo envelope, similarly as in seafloor classification using single beam ...

Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Legacy wells represent a critical consideration for offshore CO2 storage projects, as they may provide potential pathways for fluid or gas migration if poorly constructed, undocumented or inadequately abandoned. Systematically assessing large numbers of legacy wells remains challenging due to heterogeneous data availability and the diversity ...
