A network-indexbased version of TOPMODEL for use with high-resolution digital topographic data [PDF]

open access: yes, 2004
This paper describes the preliminary development of a network index approach to modify and to extend the classic TOPMODEL. Application of the basic Beven and Kirkby (1979) form of TOPMODEL to high resolution (2.0 m) laser altimetric data (based upon the ...

Tropical forests and global atmospheric change: a synthesis [PDF]

open access: yes, 2004
We present a personal perspective on the highlights of the Theme Issue 'Tropical forests and global atmospheric change'. We highlight the key findings on the contemporary rate of climatic change in the tropics, the evidence--gained from field studies--of

Summer CO2 evasion from streams and rivers in the Kolyma River basin, north-east Siberia [PDF]

open access: yes, 2013
Inland water systems are generally supersaturated in carbon dioxide (CO2) and are increasingly recognized as playing an important role in the global carbon cycle.

Changes in the soil organic carbon balance on China’s cropland during the last two decades of the 20th century [PDF]

open access: yes, 2017
Agro-ecosystems play an important role in regulating global changes caused by greenhouse gas emissions. Restoration of soil organic carbon (SOC) in agricultural soils can not only improve soil quality but also influence climate change and agronomic ...

Detecting Shifts of Monsoon Precipitation Patterns and a Large Increase in Soil Erosion Potential During 1979–2020 in Nepal

open access: yesRemote Sensing
Nepal is highly vulnerable to severe soil erosion driven by monsoonal rainfall and rugged terrains. Limitations in ground observation networks have hindered comprehensive, high-resolution national assessment of precipitation and rainfall-runoff erosivity

Dynamic resiliency analysis of key predistribution in wireless sensor networks [PDF]

open access: yes, 2009
Wireless sensor networks have been analyzed for more than a decade from operational and security points of view. Several key predistribution schemes have been proposed in the literature.

A NOVEL RESOURCE CONSTRAINT SECURE(RCS) ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORK [PDF]

open access: yesJournal of Engineering Science and Technology, 2017
Geographic routing protocols are the most preferred routing protocols for Wireless Sensor Networks (WSN) since they rely on geographic position information. Hence we propose geography based Resource Constraint Secure routing (RCS) protocol.

Focus on the impact of climate change on wetland ecosystem and carbon dynamics [PDF]

open access: yes, 2016
The renewed growth in atmospheric methane (CH4)since 2007 after a decade of stabilization has drawn much attention to its causes and future trends. Wetlands are the single largest source of atmospheric CH4.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

An acoustic view of ocean mixing [PDF]

open access: yes, 2010
Knowledge of the parameter K (turbulent diffusivity/"mixing intensity") is a key to understand transport processes of matter and energy in the ocean. Especially the almost vertical component of K across the ocean stratification (diapycnal diffusivity ...
