Phytoplankton Hotspot Prediction With an Unsupervised Spatial Community Model

, 2017
Many interesting natural phenomena are sparsely distributed and discrete. Locating the hotspots of such sparsely distributed phenomena is often difficult because their density gradient is likely to be very noisy.

Light attenuation due to preferential orientation of particles in waves and shear flow: Idealized modeling for bacteria, algae, and microplastics

Limnology and Oceanography, EarlyView.
Abstract Particles are a key component of aquatic light climate due to their attenuation of light. Near the water surface, waves and sheared currents can induce a preferential orientation of nonspherical particles that alters their inherent optical properties and the associated light attenuation.

Dominant role of benthic photosynthesis for the metabolism of carbonate sands in a subtropical inner shelf

Limnology and Oceanography, EarlyView.
Abstract Carbonate coral sands are an integral part of the carbon and nutrient cycles in subtropical and tropical coastal environments. Recent studies indicate that nearshore carbonate sands may be hotspots for organic matter production and respiration, but the processes and their controls are poorly understood due to a lack of noninvasive in situ ...

Bridging the gap between field and lab: Applicability and performance of the Sylt mesocosms facility to simulate climate change scenarios on intertidal benthic communities

Limnology and Oceanography, EarlyView.
Abstract Climate change significantly threatens coastal ecosystems, making effective conservation strategies essential and reliant on accurate data. This study employed the Sylt mesocosms facility to examine how coastal marine communities respond to both individual and combined stressors.

Nitrate, Phosphate, Silica and Phytoplankton Abundance in the Coastal Waters of Maitara Island, North Maluku

Omni-Akuatika
Nitrate, phosphate, and silica are nutrients needed for the growth of phytoplankton populations. The primary objective of the present study was to establish the relationship between the nutrient composition (nitrate, phosphate, and silica) and ...

Primary production of phytoplankton in the three types of Amazonian waters. V. Some investigations on the phytoplankton and its primary productivity in the clear water of the lower Rio Tapajós (Pará, Brazil)

, 1982
Four limnological investigations were conducted in different seasons of the years 1968 and 1969 at the lower reaches of the Rio Tapajóz. The physical and chemical parameters generally correspond with earlier findings of other authors. Midriver areas show
