Spectral absorption coefficient of phytoplankton and its relation to chlorophyll a and remote sensing reflectance in coastal waters of southern China

The spectral absorption coefficient of phytoplankton in coastal waters of southern China is investigated. Large variations in the absorption coefficient of phytoplankton are found. The absorption coefficient of phytoplankton at 443 nm ranged from 0. 006 m- 1 to 0. 484 m - 1, with an average value of 0. 067 m - 1. The chlorophyll-specific absorption coefficient of phytoplankton is also a bio-optical varito pigment composition of phytoplankton and package effect. The chlorophyll-specific absorption coefficient of phytoplankton decreases with the increasing of chlorophyll a concentration. This relationship can be described by a power law function, with the parameters and the coefficient of determination r2 as functions of wavelength, but the parameters describing the relationships in present study differed from that in Case 1 waters, thus the regional adjustment of model parameters was of particular significance for improving the accuracy of bio-optical algorithms for estimation of Chl-a concentration and primary production from remotely sensed data. Regression analysis of reflectance (R rs) ratio and absorption coefficient of phytoplankton (a ph) indicates a close correlation between them, which means that it is possible to retrieve absorption coefficient of phytoplankton using ocean color remote sensing data in optically complex coastal waters.     

厦门海区浮游桡足类卵形态与孵化率的研究

在厦门海区,调查了19种常见的自由产卵的浮游桡足类卵型及其孵化率。发现卵有二种基本型:卵表光滑和具附属刺或鞘结构。卵的形态随种类而异,即使同种也常不同。卵径大小(D)似与产卵雌体大小呈正相关;而与海区水温(t)呈负相关,并可拟合为D=a·t~b。卵孵化率具有明显的季节变化,但和卵型的相关与否则依种的不同而异,这可能与种群不同的生态适应性有关。     

广西近海污染物输运模拟研究

近年来广西近海海域赤潮现象越发频繁,对近海生态环境和海洋渔业产生的负面影响不容忽视。探索赤潮发生的机制,研究其形成机理,是有效监控赤潮和准确预测赤潮的关键。本文利用Finite Volume Coast and Ocean Model (FVCOM)模式构建广西近海水动力模型,使用步长为30 m的细网格计算广西沿海及涠洲岛附近环流,同时利用物质输运模型计算广西近海化学需氧量(Chemical Oxygen Demand,COD)的输运扩散情况。涠洲岛周围海域平均潮差约为2.4 m,最大潮差为4.8 m;平均涨潮时为13.1 h,平均落潮时为8.8 h;涨潮时最大流速为1.02 m/s,涨落潮交替时涠洲岛附近流场相当复杂,岛屿周边常常形成众多小型涡旋。污染物试验结果表明,近海河口排放COD对涠洲岛等离陆地较远的海域影响不大,而来自外海开边界的COD浓度对其作用更为明显;高浓度COD经常在涠洲岛南湾中滞留,COD等值线在涠洲岛处向南弯曲,导致涠洲岛西侧COD浓度比东侧高,而南湾和涠洲岛西北侧正是赤潮频发的地方。上述结果从动力方面表明,涠洲岛附近海域多发性的赤潮和水体富营养化与外海海水输送关系更加密切。     

低阻经络研究Ⅲ. 对经络组织学本质的推断

《低阻经络研究Ⅰ》通过用4个皮肤电极的方法测量人体阻抗,发现在健康人体体表浅层存在着低电阻带：低阻经络。《低阻经络研究Ⅱ》发现在低阻经络与体表传统经络（简称经络）的位置间有着绝非偶然的一致性,从而揭示经络具有电阻率较低的客观物性。作者进一步从低阻经络的实验数据出发,依据已被普遍接受的有关生理学结论和理论,分析了导致低阻的各种可能原因,最后推断：间液（组织液）的相对含量较高是经络低阻特性的根源,而经络的组织学本质则是疏松结缔组织里的,间液的相对含量较高的带区。

二类水体悬浮泥沙遥感反演算法综述

鉴于二类水体本身光学性质的复杂性及其与人类生产活动的密切关系,利用遥感数据监测二类水体水质受到了国内外学者的普遍关注,成为海洋学领域的热点问题。悬浮泥沙含量是表征水质优劣的一个重要参数,众多研究致力于建立悬浮泥沙反演模型的研究,定量反演二类水体悬浮泥沙浓度。该文总结了近年来二类水体悬浮泥沙遥感反演算法的研究进展。悬浮泥沙定量反演模型大致可分为以下三类：1）利用水体光学特性和水体组分之间关系建立的经验模型;2）综合经验模型和物理模型构建的半分析模型;3）基于辐射传输模型和生物光学模型建立的物理模型。针对目前反演算法存在的主要问题,提出未来的研究需加强反射率光谱曲线研究、开发高光谱遥感数据以及综合多源数据信息等方面的内容。
