Wildfires, controlled burns, and biofuel combustion (biomass burning or BB) are major contributors to particulate matter in the atmosphere and thus have an impact on climate, human health, and ecosystems. Once emitted, the particulate matter derived from B ...
This is chapter 1 of the State of Environmental Science in Svalbard (SESS) report 2022. We have used temperature measurements from a number of observatories in and above Svalbard to study temperature variations, and their relation to solar activity. Sea te ...
The temperature of the Earth is one of the most important climate parameters. Proxy records of past climate changes, in particular temperature, represent a fundamental tool for exploring internal climate processes and natural climate forcings. Despite the ...
Autonomous ballooning allows for energy-efficient long-range missions but introduces significant challenges for planning and control algorithms, due to their single degree of actuation: vertical rate control through either buoyancy or vertical thrust. Late ...
We introduce a reconfigurable medium for the manipulation of elastic propagation properties of Lamb waves. It is based on a shape memory polymer (SMP) with temperature-dependent Young's modulus. Waves are excited by a laser pulse and detected by a laser vi ...
PurposePlanar fluorescent optodes are important tools for probing key parameters, such as the soil pH, O2 level, and CO2 level, associated with the biology and biochemistry process in the rhizosphere. In this paper, we address an important limitation of ex ...
Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...
Access to safe water sources, whenever needed, is a human right. However, attending to this fundamental right remains challenging in informal settlements. Consequently, these settlements are more exposed to risk factors of several diseases related to the l ...
The main cause of flash and pluvial floods in cities is short-duration extreme rainfall events. The built environment can either intensify or weaken extreme rainfall intensity depending on the urban fabric that controls the local environmental and climatic ...
Riparian vegetation, which is commonly found in natural rivers and open channels, has a strong influence on flow structures. This paper describes a laboratory experiment on velocity distributions, secondary currents, and coherent structures in narrow open- ...
