We present a new approach to retrieve Aerosol Optical Depth (AOD) from Moderate 15 Resolution Imaging Spectroradiometer (MODIS) over the turbid coastal water. This approach 16 supplements the operational Dark Target (DT) aerosol retrieval algorithm that currently don’t 17 conduct any AOD retrieval in the regions with large water-leaving radiances in the visible spectrum. 18 Over the global coas...

A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most economically developed cities in China, has experienced a ...

Increasing population size and economic dependence on the coastal zone, coupled with growing need for residential, agricultural, industrial, commercial green space infrastructure, are key drivers of land reclamation. Until now, there has been no comprehensive assessment global distribution use reclaimed at coast. Here, we analyze Landsat satellite imagery from 2000 to 2020 quantify spatial exte...

To investigate the effect of arable land protection policies in China, a practical framework that integrates geographic information systems (GIS), soil quality assessment and landscape metrics analysis was employed to track and analyze arable land transformations and landscape changes in response to rampant urbanization within the Ningbo region (China) from 2005 to 2013. The results showed that...

This work aimed to understand the distribution of five bacterial pathogens in O'ahu coastal streams and relate their presence to microbial indicator concentrations, land cover of the surrounding watersheds, and physical-chemical measures of stream water quality. Twenty-two streams were sampled four times (in December and March, before sunrise and at high noon) to capture seasonal and time of da...

Some land and ocean processes are related through connections (and synoptic-scale teleconnections) to the atmosphere. Synoptic-scale atmospheric (El Niño/Southern Oscillation [ENSO], Pacific Decadal Oscillation [PDO], and North Atlantic Oscillation [NAO]) decadal cycles are known to influence the global terrestrial carbon cycle. Potentially, smaller scale land-ocean connections influenced by co...

Coastal areas are rapidly developing due to population growth and the appeal of coastlines. In order to gain insight into how land use/cover affects carbon (C) storage in a coastal context, we examined soil and vegetation C and soil nitrogen (N) across land uses near Apalachicola, FL. Forested wetlands had the greatest soil C and N storage, while natural pine forests and pine plantations had th...

This study analyzed land use and land cover changes and their impact on land surface temperature using Landsat 5 Thematic Mapper and Landsat 8 Operational Land Imager and Thermal Infrared Sensor imagery of the Yellow River Delta. Six Landsat images comprising two time series were used to calculate the land surface temperature and correlated vegetation indices. The Yellow River Delta area has ex...

The seed for this collaborative project has been the Land-Ocean Interaction in the Coastal Zone [LOICZ] typology group: a loosely organized set of researchers examining and estimating fluxes in basic nutrients in the coastal zone [1] This prior work has resulted in a well-defined process and a set of stand-alone and web-based tools for automatic typology development with geospatial data sets [3...
