One of the goals of the Vrokastro Survey Project, based in west-central Mirabello, eastern Crete, was to identify a site within the boundaries of the survey study area worthy of further investigation, including excavation. The settlement selected, based on its complexity and long lifespan, was Priniatikos Pyrgos, a harbour community and ‘gateway’ of the Vrokastro region. As a preliminary to excavation, the Istron Geoarchaeological Project was initiated in order to document the nature, condition, and resources of this site and its coastal environment. This multidisciplinary program was implemented through fieldwork, laboratory analyses, and geophysical prospection. Results include new data concerning the industrial aspects of Priniatikos Pyrgos, the changing topographical situation of the site and coastal zone, the overall size of this diachronic harbor settlement, and the regional resources involved in ceramic and metallurgical production.

В статье приводятся результаты экспериментальных исследований распространения низкочастотных акустических сигналов (33 Гц) на побережье залива Петра Великого Японского моря. Источник акустических сигналов опускался с борта маломерного судна в воду, а приемные системы были у береговой черты в воде и на суше. За счет использования трехкомпонентных виброметров стало возможно разделить принятые сигналы на различные типы волн (продольные, поперечные и поверхностные). Получены предварительные результаты расчета скоростных характеристик приходов различного типа волн на виброметры. The article presents the results of experimental studies on the propagation of low-frequency acoustic signals (33 Hz) on the coast of Peter the Great Bay of the Sea of Japan. The source of acoustic signals descended from the board of a small boat into the water, and the receiving systems were at the coastline in water and on land. Through the use of three component vibrometers, it has become possible to divide the received signals into various types of waves (longitudinal, transverse and surface waves). The preliminary results of calculating the speed characteristics of the arrival of various types of waves on vibrometers are obtained.

Simply knowing the geographic extent of sediment contamination within a bay or estuary does not provide sufficient insight to help a site manager or stakeholder begin to assess how to manage sediments deemed either an ecological risk or regulatory violation. A better approach is to assess contaminant distribution and behavior at a micro-scale in parallel with macro-scale site assessments. In such an approach, a site investigation includes an assessment of contaminant/sediment biogeochemistry, as it will impact bioavailability, risk, and potential management options. This paper reviews some approaches for assessing contaminant bioavailability, distribution and degradability, and presents preliminary results from some biogeochemical sediment assays. Some of the potential uses and limitations of such assays are discussed. Selective leaches, using alcohol or digestive juices to determine bioavailable contaminant fractions still require some validation. Assessments of contaminant distribution as a function of grain size can lend insight into both contaminant mobility and management strategies. Biodegradation studies in real sediments are complicated by analytical and heterogeneity difficulties, but can, if carried out carefully, provide useful information.
