Storms can be both destructive and valuable at the same time. They expose coastal areas to various risks but can also enhance the supply of wind energy and provide marine ecosystems with oxygen rich water. As the North Atlantic Oscillation (NAO) is known to have a significant impact on the wind climate in Europe, investigating its interconnection to storm frequency and intensity under global warming circumstances in the Northern Baltic Sea region was of interest in this study. Wind speed data se...

When he began his journal seaman Hugh Calhoun had high hopes for the outward-bound voyage ahead of him. Ship-of-the-Line Ohio was back from the Siege of Veracruz, being prepared for her next mission, and the War was at its height. The cruize, as he called it, did not turn out as eventful as he expected it to be and yet he was nevertheless able to produce a book which bountifully embodies a short but fruitful chapter of maritime literary history. Serio-Comic Journal of a Cruize, On Board of the ...

Interest in commercial sea urchin aquaculture is growing worldwide. This is because sea urchins have good quality roe which is a delicacy in many countries. Since the quality of sea urchin roe is dependent on what the sea urchin eats, increased research is being carried out to understand sea urchin feeding preferences. Feeding preference is related to the attractiveness/palatability of the feed, which is thought to be based on its chemical composition. Since an unpalatable feed will result in th...

Includes bibliographical references. / Sea surface temperature (SST) fluctuations and changes around southern Africa have important consequences on regional weather, climate and the marine ecosystem. SST is a good indicator for upwelling strength in the Benguela Current system and therefore is linked to bio logical activity in that region. SS T is an important driver of the air-sea exchange of moisture and energy, especially in the Agulhas Current where high latent and sensible heat fluxes occur...

Resolving diversity patterns and their underlying drivers has application for both ecological theory and ocean management. Because seafloor characteristics are often used to assess bottom habitat, I examined the relationship between deep-sea benthic (bottom-living) diversity and multi-scale topographic heterogeneity. Most work occurred on the Canadian Pacific continental shelf at Learmonth Bank with additional sites in Strait of Georgia (BC) and Gulf of Maine (Atlantic shelf). High-resolution sp...

Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. However, even though evolution can occur rapidly there are only few examples of genetic adaptation to climate change. In my thesis, I used a near-natural system to study if and how organisms have adapted to 30 years of warming, and...

This work is focused on the analysis of sea–level change (last century), based mainly on instrumental observations. During this period, individual components of sea–level change are investigated, both at global and regional scales. Some of the geophysical processes responsible for current sea-level change such as glacial isostatic adjustments and current melting terrestrial ice sources, have been modeled and compared with observations. A new value of global mean sea level change based of tide ga...

Co-evolution between parasites and their hosts result in extremely well-orchestrated and intimate relationships that are characterized by remarkable adaptations in the attack response of the parasite and the defense response of the host. To fully understand host-parasite interactions, these adaptations must be considered in the context of the ecological constraints in which they evolved. As a serious pest to salmon mariculture, Lepeophtheirus salmonis has been extensively studied; however, there...

Climate change predictions indicate that increased future rainfall in the north of Europe will result in elevated land run off, thus allochthonous material transported to the Baltic Sea will increase. Consequently, compounds including humic substances, organic matter and inorganic nutrients (N and P), all with different biological availabilities, will be transferred to the sea. Such compounds will be incorporated differently into the food web, influencing primary (PP) and bacterial (BP) producti...

Motivation behind the spring whale shark (Rhincodon typus) aggregation in Al-Lith, on the Saudi Arabian coast of the South Central Red Sea, is uncertain. A plausible hypothesis is that whale sharks gather to feed on high prey density, leading to questions about the cause of the prey density. A bottom-up process fueled by nutrient input or accumulation from physical advection could create a peak in prey biomass. Wastewater discharged from an aquaculture facility could affect productivity or provi...

Between 33 and 91 percent of marine species are currently undescribed, with the majority occurring in tropical and offshore environments. Sponges act as important microhabitats and promote biodiversity by harboring a wide variety of macrofauna and microbiota, but little is known about the relationships between the sponges and their symbionts. This study uses DNA barcoding to examine the macrofaunal communities associated with sponges of the central Saudi Arabian Red Sea, a drastically understudi...

碩士 / 國立臺灣大學 / 海洋研究所 / 94 / From the previous hydrographic and numerical studies, the finding of a year round northeastward flowing South China Sea Warm Current (SCSWC) existed on the continental shelf of northern South China Sea (SCS), even during the NE monsoon season has been claimed. However, the existence and mechanism of SCSWC is still controversial because the conclusion is mostly based on one-time hydrographic survey or very short-term moored current velocity measurements. In this study...

Ocean acidification is predicted to have adverse effects on the physiologies of marine organisms, particularly those that produce calcified structures. Extracellular homeostasis is considered to be critical to mediating the effects of ocean acidification. Due to their low metabolic rates and weak ability to regulate ion exchange, sea urchins are thought to be particularly weak acid-base regulators. Recent findings showing species-specific capacities for extracellular pH regulation however sugges...

Seagrass ecosystems are intense carbon sinks, but they can also emit greenhouse gases (GHG), such as carbon dioxide (CO2) and methane (CH4), to the atmosphere. Yet, GHG emissions by seagrasses are not considered when estimating global CH4 production rates by natural sources, although these estimations will help predict future scenarios and potential changes in CH4 emissions. In addition, the effect of warming on GHG emissions by seagrasses has not yet been reported. The present study aims to ass...
