Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Projected cross-shore changes in upwelling induced by offshore wind farm development along the California coast

Communications Earth & Environment, 2023
In California offshore waters, sustained northwesterly winds have been identified as a key resource that can contribute substantially to renewable energy goals. However, the development of large-scale offshore wind farms can reduce the wind stress at the

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

Oikos, EarlyView.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Nitrogen nutrition of harmful algal blooms in upwelling systems [PDF]

, 2009
Blooms of toxic, or otherwise harmful phytoplankton species are known to occur in eastern boundary upwelling systems, coincident with the relaxation of upwelling in latesummer/autumn.

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...

Responses of Summer Upwelling to Recent Climate Changes in the Taiwan Strait

Remote Sensing, 2021
The response of a summer upwelling system to recent climate change in the Taiwan Strait has been investigated using a time series of sea surface temperature and wind data over the period 1982–2019.

Coastal upwelling in a warmer future

Geophysical Research Letters, 2002
Coastal upwelling helps set the physical context for marine ecosystems, and upwelling zones are among the most productive regions of the global ocean. Unlike earlier models, two state‐of‐the‐art climate models exhibit little change during the next century in the magnitude and seasonality of coastal upwelling, but climate models are still probably not ...

Sublittoral soft bottom communities and diversity of Mejillones Bay in northern Chile (Humboldt Current upwelling system) [PDF]

, 2006
The macrozoobenthos of Mejillones Bay (23°S; Humboldt Current) was quantitatively investigated over a 7-year period from austral summer 1995/1996 to winter 2002.

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

Driving mechanisms of the Port Alfred upwelling cell inshore of the Agulhas Current [PDF]

, 2013
The presence of a semi-permanent upwelling cell, with a surface expression more than 40 % of the time has previously been described inshore of the Agulhas Current in the vicinity of Port Alfred, South Africa.
