Ecology of foraminifera during the middle Eocene climatic optimum in Kutch, India

open access: yesGeodinamica Acta, 2017
The shallow marine carbonates of Kutch temporally correspond to the globally recognised warming period called Middle Eocene Climatic Optimum (MECO) that extended from later part of planktic foraminiferal zone E11 to E12 and Shallow Benthic Zone (SBZ) 17.

Temporal patterns of Deepwater Horizon impacts on the benthic infauna of the northern Gulf of Mexico continental slope.

open access: yesPLoS ONE, 2017
The Deepwater Horizon oil spill occurred in spring and summer 2010 in the northern Gulf of Mexico. Research cruises in 2010 (approximately 2-3 months after the well had been capped), 2011, and 2014 were conducted to determine the initial and subsequent ...

Future Arctic Ocean Seasonal Ice Zones and Implications for Pelagic-Benthic Coupling [PDF]

open access: yesOceanography, 2011
Despite concerns about rapid changes in Arctic Ocean physical forcing and ecosystem function, quantitative knowledge and time series are scarce. The number of reliable physical-biological coupled models and models based on remote sensing is small. To improve our comprehension of carbon flux in the most prominent Arctic Ocean feature, the seasonal ice ...

What is “accuracy”? Rethinking machine learning classifier performance metrics for highly imbalanced, high variance, zero‐inflated species count data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Machine learning has opened the door for the automated sorting (classification) of images, holograms and acoustic backscatters of individual plankton, invertebrates, fish and marine mammals. However, this field is complicated by decades of paradoxically promising reports of classifier performance that do not correlate with real‐world uptake of

Westernmost Mediterranean records of three gobiid species (Actinopterygii: Perciformes: Gobiidae) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2019
Information on the distribution of small benthic fish such as gobies is sometimes scattered or incomplete. This is probably due to the sampling difficulties involved in the study of these small fishes at depths below those accessible for SCUBA diving ...

Benthic oxygen exchange in a live coralline algal bed and an adjacent sandy habitat: an eddy covariance study [PDF]

open access: yes, 2015
Coralline algal (maerl) beds are widespread, slow-growing, structurally complex perennial habitats that support high biodiversity, yet are significantly understudied compared to seagrass beds or kelp forests.

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...

Survey on Macro-Zoobenthic resource in Seyahdarvishan and Passikhan Rivers, Potamon Zone (Quantitative) Page 8-20

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1995
The Rivers Seyahdarvishan and Passikhan are the main two rivers which evacuate water to Anzali coastal lagoon. The two rivers has sustain flow in potamon zone with only variations in rate during spring and autumn season.
