Red tides of the dinoflagellate Noctiluca scintillans associated with eutrophication in the Sea of Marmara (the Dardanelles, Turkey)

open access: yes, 2013
This investigation focused on weekly variations in cell density and volume of the dinoflagellate Noctiluca scintillans between March 2001 and January 2004 in the Dardanelles. March–June and October–December periods were excessive bloom periods.

Low Surface Brightness Imaging of the Magellanic System: Imprints of Tidal Interactions between the Clouds in the Stellar Periphery

open access: yes, 2016
We present deep optical images of the Large and Small Magellanic Clouds (LMC and SMC) using a low cost telephoto lens with a wide field of view to explore stellar substructure in the outskirts of the stellar disk of the LMC (r < 10 degrees from the ...

Las Mareas Rojas

open access: yesEDIS, 2008
ENY-851S, a 5-page illustrated fact sheet by Jorge R. Rey, is the Spanish version of ENY-851, “Red Tides” (forthcoming). It explains what these “harmful algal blooms” are, what causes them, their impacts on marine ecosystems, human health, and coastal ...

Tracing the early development of harmful algal blooms with the aid of Lagrangian coherent structures

open access: yes, 2007
Several theories have been proposed to explain the development of harmful algal blooms (HABs) produced by the toxic dinoflagellate \emph{Karenia brevis} on the West Florida Shelf.

Patterns of paralytic shellfish toxicity in the St. Lawrence region in relationship with the abundance and distribution of Alexandrium tamarense

open access: yesScientia Marina, 2003
Shellfish toxin data from 11 years and Alexandrium tamarense abundance during 6 of those years are analysed. Comparison of PSP toxicity in Mytilus edulis with PSP toxicity in Mya arenaria shows a significant correlation (r2=0.61), with M.

Deadly dark matter cusps vs faint and extended star clusters: Eridanus II and Andromeda XXV

open access: yes, 2017
The recent detection of two faint and extended star clusters in the central regions of two Local Group dwarf galaxies, Eridanus II and Andromeda XXV, raises the question of whether clusters with such low densities can survive the tidal field of cold dark

Ocean Color Quality Control Masks Contain the High Phytoplankton Fraction of Coastal Ocean Observations

open access: yesRemote Sensing, 2019
Satellite estimation of oceanic chlorophyll-a content has enabled characterization of global phytoplankton stocks, but the quality of retrieval for many ocean color products (including chlorophyll-a) degrades with increasing phytoplankton biomass in ...

The influence of general-relativity effects, dynamical tides and collisions on planet-planet scattering close to the star

open access: yes, 2019
Planet--Planet scattering is an efficient and robust dynamical mechanism for producing eccentric exoplanets. Coupled to tidal interactions with the central star, it can also explain close--in giant planets on circularized and potentially misaligned ...

The IOC International Harmful Algal Bloom Program: History and Science Impacts [PDF]

open access: yesOceanography, 2010
Harmful algal blooms (HABs) have become an important subdiscipline within oceanography. Heightened attention to this topic as well as significant research advances reflect the global nature of the problem and the development of strong national and ...
