The vertical distribution of fish on two offshore oil platforms

Frontiers in Marine Science
Knowledge of platform ecology is necessary to best inform decommissioning practice. Remotely operated vehicle (ROV) video is often collected during standard industry operations and may provide insight into the marine life associating with offshore ...

Vertical dynamic patterns of Vibrio spp. in the northwestern Pacific Ocean

Frontiers in Microbiology
In marine ecosystems, Vibrio species are as they facilitate nutrient cycling and impact the condition of marine life. To understand their ecological dynamics and how they adapt to various environmental situations, this study examined the vertical ...

Vertically Exported Phytoplankton (< 20 µm) and Their Correlation Network With Bacterioplankton Along a Deep-Sea Seamount

Frontiers in Marine Science, 2022
Phytoplankton have been observed to be widely distributed in the oceanic vertical water columns and have an important contribution to carbon sequestration via biological pump mechanism. However, in seamount areas with strong hydrodynamics, their vertical

The vertical distribution of chlorophyll [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1960
The vertical distribution of chlorophyll in the sea generally shows a maximum concentration at a depth which may vary from at or just below the surface, to near or below the bottom of the euphoric zone. The easiest distributions to explain are those where the maximum chlorophyll concentration is at or very near the surface.

Multi-Dimensional Estimation of Leaf Loss Rate from Larch Caterpillar Under Insect Pest Stress Using UAV-Based Multi-Source Remote Sensing

Drones
Leaf loss caused by pest infestations poses a serious threat to forest health. The leaf loss rate (LLR) refers to the percentage of the overall tree-crown leaf loss per unit area and is an important indicator for evaluating forest health.

Crossover of the weighted mean fragment mass scaling in 2D brittle fragmentation

, 2004
We performed vertical and horizontal sandwich 2D brittle fragmentation experiments. The weighted mean fragment mass was scaled using the multiplicity $\mu$. The scaling exponent crossed over at $\log \mu_c \simeq -1.4$.

Air mass factor formulation for spectroscopic measurements from satellites: Application to formaldehyde retrievals from the Global Ozone Monitoring Experiment [PDF]

, 2001
. We present a new formulation for the air mass factor (AMF) to convert slant column measurements of optically thin atmospheric species from space into total vertical columns.

Seasonal dynamics and vertical distribution of ecosystem-level carbon stocks in different vegetation types of the Minjiang estuary wetland

Frontiers in Marine Science
Coastal wetlands play a crucial role in the global carbon cycle and climate regulation by serving as significant reservoirs of ecosystem carbon stock. However, their carbon sequestration capacity is strongly influenced by vegetation types, as well as the

Zooplankton abundance, species composition and ecology of tropical high-mountain crater lake Wonchi, Ethiopia

Journal of Limnology, 2014
The highlands of Ethiopia represent some of the remnants of undisturbed aquatic ecosystems; they are however highly threatened by significant socio–economic developments and associated anthropogenic impacts. Lake Wonchi is one of the few remaining fairly
