Assessment of the post-fire forest restoration dynamics in the Olekminsky State Nature Reserve (Russia) according to data of Landsat satellite images [PDF]

Nature Conservation Research, 2019
The use of time series of satellite images allows us to trace the dynamics in the processes of reforestation and forest formation. We estimated the use of the results of cluster analysis of the pixel distribution in the monitoring of post-fire forest restoration.

A transferable satellite-derived bathymetry model without site-specific calibration for Case-1 optically shallow waters using Sentinel-2/MSI imagery

GIScience & Remote Sensing
Accurate bathymetry in optically shallow waters (OSWs), particularly across coral reef environments, is essential for coastal ecosystem management and benthic habitat monitoring.

Rotational dynamics of irregularly shaped natural satellites

The Astronomical Journal, 1987
The rotational histories of irregularly shaped satellites are studied and are found to differ from the standard picture of tidal evolution of satellite rotations. Prior to capture into the synchronous rotation resonance, a narrow attitude-unstable chaotic zone is entered and the satellite begins to tumble chaotically.

Variability in the Sea Surface Temperature Gradient and Its Impacts on Chlorophyll-a Concentration in the Kuroshio Extension

Remote Sensing, 2021
Sixteen years of satellite observational data in the Northwestern Pacific Ocean are used to describe the variability in the sea surface temperature (SST) gradient and its impact on chlorophyll-a concentrations (Chl-a).

Dynamics in mangroves assessed by high-resolution and multi-temporal satellite data: a case study in Zhanjiang Mangrove National Nature Reserve (ZMNNR), P. R. China [PDF]

Biogeosciences, 2013
Abstract. Mangrove forests are declining across the globe, mainly because of human intervention, and therefore require an evaluation of their past and present status (e.g. areal extent, species-level distribution, etc.) to implement better conservation and management strategies. In this paper, mangrove cover dynamics at Gaoqiao (P. R.

Remote Sensing of the Seasonal and Interannual Variability of Surface Chlorophyll-a Concentration in the Northwest Pacific over the Past 23 Years (1997–2020)

Remote Sensing, 2022
Phytoplankton in the northwest Pacific plays an important role in absorbing atmospheric CO2 and promoting the ocean carbon cycle. However, our knowledge on the long-term interannual variabilities of the phytoplankton biomass in this region is quite ...

Predicting and Understanding the Pacific Decadal Oscillation Using Machine Learning

Remote Sensing
The Pacific Decadal Oscillation (PDO), the dominant pattern of sea surface temperature anomalies in the North Pacific basin, is an important low-frequency climate phenomenon. Leveraging data spanning from 1871 to 2010, we employed machine learning models

Effects of Semistochastic Westerly Wind Bursts on ENSO Predictability

Geophysical Research Letters, 2020
Westerly wind bursts (WWBs) occurring over the tropical Pacific play an important role on El Niño‐Southern Oscillation (ENSO) dynamics. Currently, climate models have significant biases in their representation of WWBs, which may limit their ability to ...
