Deep refuges: the distribution of marine fish in warming subtropics

open access: yesEcography, EarlyView.
In light of global climate change, identifying critical marine habitats and conserving them is essential. Marine conservation planning recommends designating cooler habitats as marine protected areas. The ‘deep‐reef refugia' hypothesis suggests that deeper, suitable habitats may allow species to undergo the evolutionary changes necessary to adapt to ...

Development of marker detection method for estimating angle and distance of underwater remotely operated vehicle to buoyant boat

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2021
The paper proposes a Marker Detection Method for Estimating the Angle and Distance of Underwater Remotely Operated Vehicle (ROV) to Buoyant Boat. To keep the ROV aligned with the boat, a marker and visual recognition system are designed.

Depth‐structured sponge assemblages offer limited evidence for mesophotic refuge potential under the deep reef refuge hypothesis

open access: yesEcography, EarlyView.
Temperate mesophotic ecosystems (TMEs) have the potential to act as climate refugia for shallower benthic species impacted by environmental change. However, the extent to which mesophotic ecosystems might provide an ecological refuge, particularly for key functional groups like sponges, remains poorly known in temperate systems.

Simulasi Dan Analisa Dinamika Remotely Operated Vehicle (Rov) [PDF]

open access: yes, 2015
ROV (Remotely Operated Vehicle) is a type of underwater robot that resembles a ship. The robot is controlled by a pilot who controls the remote control. In this ROV tether as a link robot using the device as a source of energy on the surface of the ocean,

Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

LASER POSTERIOR CAPSULOTOMY IN CASE OF THE 1ST DEGREE OF POSTERIOR CAPSULAR OPACITY OF THE LENS IN PSEUDOPHAKIC EYES

open access: yesОфтальмохирургия, 2015
Purpose. To identify indications for laser posterior capsulotomy in case of the 1st degree of posterior capsular opacity (PCO) of the lens in pseudophakic eyes.Material and methods. The study was carried out in 43 patients (43 eyes) aged 45-74 years old,

A universal genome sequencing method for rotavirus A from human fecal samples which identifies segment reassortment and multi-genotype mixed infection

open access: yesBMC Genomics, 2017
Background Genomic characterization of rotavirus (RoV) has not been adopted at large-scale due to the complexity of obtaining sequences for all 11 segments, particularly when feces are used as starting material.

Comparative Population Genetics of Two Alvinocaridid Shrimp Species in Chemosynthetic Ecosystems of the Western Pacific

open access: yesIntegrative Zoology, EarlyView.
Little is known about the population divergence and gene flow of deep‐sea animals living in disjunct hydrothermal vents and cold seep habitats. Taking advantage of samples collected from multiple cruises across a huge distance of >5000 km, we revealed the differential population divergence pattern and gene flow in two congeneric species of shrimps ...
