Photosynthetic primary production in the Mesoproterozoic

New Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Observations of Backscatter from Sand and Gravel Seafloors Between 170-250 kHz [PDF]

, 2015
Interpreting observations of frequency-dependence in backscatter from the seafloor offers many challenges, either because multiple frequencies are used for different observations that will later be merged or simply because seafloor scattering models are ...

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

Restoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

A procedure for developing an acceptance test for airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]

, 2013
National Oceanic and Atmospheric Administration (NOAA) hydrographic data is typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for near‐shore areas.

Opportunities for targeted, small‐scale law reform in marine and coastal restoration

Restoration Ecology, EarlyView.
Across the globe, law reform is being considered as a mechanism to support, guide, and encourage the upscaling of ecological restoration. While high‐profile examples like the European Nature Restoration Law show the value of large‐scale law reform, this scale of law reform will not be feasible or politically tractable everywhere.

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Bioturbating bivalves show potential to bioremediate degraded soft sediments by restoring ecosystem function

Restoration Ecology, EarlyView.
Abstract Introduction Natural recovery of disturbed marine ecosystems can take years, mainly because long‐lived, functionally important species are lost. To regain ecosystem services, the focus of estuarine restoration is shifting from biodiversity metrics to functional restoration.

Specialized Committees of International Organizations an Important Source of Organizational Autonomy

Regulation &Governance, EarlyView.
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show
