Traditionella metoder fö r vattenkvalitetssä kring, som anvä nds idag, innefattar manuell provtagning fö ljt av laboratorieanalys.

The goal of this dissertation is to provide a comprehensive study of scenes of fresh water in Minoan art from the Middle Minoan II (MM II) through the Late Minoan I (LM I) periods. This dissertation addresses and fills the gap in the scholarship regarding the depiction of riparian environments and the special place of these depictions in Aegean art. It also attempts to clarify the use and function of riverscapes across chronological periods. Rivers, marshes, streams, and springs, appear on a variety of media and fulfil multiple functions from MM II onward. Images of fresh water were used as topographical markers, ornamentation and decoration, and for religious purposes. Moreover, several images suggest that the Minoans may have believed that the realm for the goddess (or one of the goddesses) was a lush, riverscape. A second goal of this dissertation is to clarify and dispose of the term “Nilotic” as a label for images of fresh water in the Aegean. Since its introduction into the literature of Aegean studies in the beginning of the 20th century, the term “Nilotic” has been used inconsistently to describe Aegean scenes of fresh water that may or may not contain Egyptian elements. This assumption has led some scholars to state that Aegean riverscapes are ultimately derived from Egyptian scenes of fishing and fowling because they share similar iconographic elements. Unfortunately, the process of synthesis is important to the understanding of Aegean riverscapes, and iconographic similarities are somewhat superficial. Furthermore, the term has been used without regard for a long-standing tradition of the depiction of riparian environments in Bronze Age Aegean art. To fully address both goals of this project, the origin of individual iconographic elements has been traced through various media, including glyptic art, pottery, and wall painting. Wall paintings from the Cyclades and some Late Helladic IA scenes have been included when appropriate. Whenever possible, categories of riverscapes have been grouped together, but each wall painting, has been examined and interpreted individually. Some unique, highly pictorial, and detailed images in other media have also been addressed separately. Parallels in Egyptian and, in some cases, Near Eastern art have been sought to determine the validity of the term “Nilotic,” and a special study of Egyptian scenes of hunting in the marshes has been conducted in comparison to Aegean scenes. Iconography, synthesis, and context have all been taken into consideration.

Повний текст джерелаIt is found that under present-day climatological surface forcing the system may oscillate at interdecadal period. The mechanism driving the oscillations is linked to changes in both the horizontal and vertical extent of convection in the northern "Labrador Sea". The structure of the surface freshwater flux forcing plays a major role in both the initiation and sustenance of the interdecadal oscillations. Allowing for a freshwater flux into the northern region of the "Labrador Sea" inhibits the interdecadal variability. The oscillations, however, appear, relatively insensitive to Arctic fresh water transport into the "Greenland Sea".
A detailed three-dimensional discussion of the physics behind the interdecadal oscillations is presented.

Повний текст джерелаLa capacité des milieux humides à séquestrer du carbone a beaucoup attiré l'attention, notamment dans le contexte des changements climatiques. À ce jour, bien que plusieurs études aient été menées sur les tourbières, très peu portent sur les marais. Cette étude a utilisé la technique de covariance des turbulences afin de mesurer l'échange écosystémique net (EEN) de CO2 et l'échange d'énergie d'un marécage de quenouilles de l'est de l'Ontario, Canada. Les objectifs de cette étude étaient d'utiliser un ensemble de données de quatre ans afin de déterminer les contrôles environnementaux sur la variabilité des échanges de carbone et de vapeur d'eau. Le EEN annuel cumulé était en moyenne de -246 ± 26,8 gCm-2a-1 allant de -216 à -260 gCm-2a-1. La variabilité de l'accumulation entre les années était le résultat de la synchronisation du printemps et de l'automne au niveau de l'absorption du carbone et de la longueur des saisons de croissance, chacune ayant été déterminée par les conditions météorologiques qui prévalaient. L'étude de la variabilité interannuelle a indiqué que le marécage pourrait être sensible aux pertes de C causées par une augmentation de la respiration au cours de périodes plus chaudes d'automne. Les valeurs moyennes quotidiennes maximales d'évapotranspiration (ET) ont atteint 10,75, 9,07, 11,70 et 8,36 mm jour-1 en 2005, 2006, 2007 et 2008 respectivement. Les valeurs du rapport de Bowen variaient selon la saison, avec des valeurs bien en dessous de l'unité pendant la saison de croissance (mai à octobre), illustrant la dominance de la chaleur latente. Une évaluation de la fraction d'évaporation et du facteur α de Priestley-Taylor indiquaient l'importance saisonnière de l'ET et les valeurs élevées de mi-saison du facteur de découplage (Ω) indiquaient que l'ET du marais est dominé par les radiations en raison de sa surface aérodynamique lisse et de l'abondance d'eau. Dans l'ensemble, l'écosystème du marais était un grand puits de carbone annuel par rapport aux écosystèmes de tourbière et les taux d'ET étaient fortement dépendants de l'apport radiatif.

The Lower Charles River has been a heavily utilized urban river that runs between Cambridge and Boston in Massachusetts. The recreational usage of the river is dependent on adequate water depths and there have been no definitive prior studies on the sedimentation rate of the Lower Charles River. The river transitioned from tidal to a freshwater basin in 1908 and the study area for historical comparisons was from the old Charles River Dam to the Boston University Bridge. This study surveyed the river, digitized three prior surveys that spanned 114 years, calculated volumes and depth distributions for each survey, and estimated sedimentation rates from fits to the volumes over time. The average sedimentation rate is estimated as 5-10 mm/year, which implies 1.8-3.5 feet sedimentation since 1908. Sedimentation rates and distributions are necessary to develop comprehensive management plans for the river.
