In recent years, airborne lidar has been used in a wide range of oceanic applications, including detection bathymetry, bubbles, internal waves, and schools fish. However, it not yet extensively applied Chinese seas. For example, there have no studies to detect subsurface plankton layers the South China Sea (SCS) by lidar. this study, we investigated technology's applicability for identifying Sanya Bay, SCS. Three flight experiments were carried out March 2018 September 2017. Shipboard...
Detecting the vertical profile of optical properties is an important task in remote sensing upper ocean, especially for 3-D reconstruction. Ocean color can only provide surface information, while light detection and ranging (lidar) technique depth-resolved data. Lidar global-scale observations ocean days nights with minimal atmospheric correction errors. Unfortunately, due to strong multiple scattering effects that occur when propagates seawater, simple lidar equation may cause some...
Abstract In estuarine and coastal ecosystems, the majority of previous studies have considered coupled nitrification-denitrification (CND) processes to be exclusively sediment based, with little focus on suspended particulate matter (SPM) in water column. Here, we present evidence CND column Hangzhou Bay, one largest macrotidal embayments world. Spearman’s correlation analysis showed that SPM was negatively correlated nitrate ( rho = −0.372, P 0.018) marker genes for nitrification...
Retrieving the water depth by satellite is a rapid and effective method for obtaining underwater terrain. In optical shallow waters, bottom signal has great impact on radiation from which related to depth. spatial distribution characteristic of quality parameters derived updated quasi analysis algorithm (UQAA) highly correlated with brightness. Because reflection strongly depth, may helpful applicable remote sensing based bathymetry. Therefore, influence bathymetry retrieval UQAA IOPs worth...
This paper presents a new approach to multiscale segmentation of satellite multispectral imagery using edge information. The Canny detector is applied perform detection. detected features are then utilized in loop, and the merge procedure for adjacent image objects controlled by separability criterion that combines information with scale. significance measured partitioned regions assessment. present method based on half-partition structure, which composed three steps: single detection,...
A novel remote sensing algorithm was developed based on Landsat 8 Operational Land Imager (OLI) data to separately recognize concurrent Sargassum and Ulva prolifera in the South Yellow Sea. This has three main steps: 1) classification of macroalgae-containing pixels from normal seawater by means a mature floating algae index (FAI) approach; 2) first-round separate recognition targets using newly "Sargassum Index I (SUI-I)" method; 3) further fine identification applying another new (SUI-II)...
Multifunctional diimidazole, 2,6-bis[(imidazol-1-yl)methyl]-4-methylphenol (BIP), was crystallized with different dicarboxylic acids, such as oxalic acid (OA), isophthalic (IPA), and terephthalic (TPA), affording crystals of (BIP2+)·(OA2-) (1), (BIP)·(IPA) (2), (BIP)·(TPA) (3), (BIP)·(TPA)0.5 (4). X-ray single-crystal diffraction studies reveal that all four organic contain strong classical hydrogen bonds (such O−H···N, O−H···O, etc.), which are usually observed in cocrystals carboxylic...
A novel metal-organic framework with one-dimensional channels {[Cd(3)(CH3COO)2(H2O)2] (CH3CN)x(CH3OH)y} (5), based on conformationally restricted linear 4,4′-bis(1-imidazolyl)biphenyl (3) and cadmium acetate dihydrate, has been synthesized. It crystallizes in the triclinic system, space group P1̅ a = 5.6528(11) Å, b 9.887(3) c 12.924(3) Z 1. The experimental results demonstrate that coordinated crystal water molecules may play key role formation of frameworks.
Knowledge about the spatiotemporal distribution of sea surface salinity (SSS) provides valuable and important information for understanding various marine biogeochemical processes ecosystems, especially those coastal waters significantly affected by human activities. Remote-sensing techniques have been used to monitor in open ocean with their advantages wide-area surveys real-time monitoring. However, potential challenges remain when using satellite data coarse resolutions, leading a loss...
Qiandao Lake is located in the northern edge of subtropics, and its water body thermally stratified summer. It great scientific significance to study vertical physical chemical indexes phytoplankton characteristics reveal aquatic ecosystem structure lake. Conventional observation uses in-situ profile instruments, which time consuming labor intensive. In recent years, lidar has shown increasing oceanic applications; however, it not yet been extensively applied inland water. There are no...
Oceanic lidar is an effective tool for detecting water's vertical structure. Cost-effective design of oceanic system and processing algorithms requires simulator. In this study, simulation was developed, which available to the public ( <uri xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">https://github.com/soedchen/OLE</uri> ), named Lidar Emulator (OLE). OLE improved semianalytic Monte Carlo-based simulator, has capability dealing with physics light...
Water depth estimation in seaports is essential for effective port management. This paper presents an empirical approach water determination from satellite imagery through the integration of multiple datasets and machine learning algorithms.
