Specialization and economic impact of the ports of Montreal,Quebec, Saint John,and Halifax

Specialization in cargoes and forelands is defined for the ports of Montreal, Quebec, Saint John, and Halifax using a variation of the location quotient. Economic impact is also defined using the location quotient. All ports are shown to have some degree of specialization; whereas, Saint John and Halifax have relatively greater economic impact. It is suggested that the four ports should be encouraged to develop their specializations. However, are the benefits to the shipping industry in following such a policy outweighed by the losses to the local economies because investment in certain ports does not take place?

Synoptic transects on the distribution of trace elements (Hg,Pb, Cd,Cu, Ni,Zn, Co,Mn, Fe,and Al) in surface waters of the Northern- and Southern East Atlantic

Surface seawater samples were taken in the framework of the GEOTRACES program on “POLARSTERN” expedition ANT XXIII/1 in the Eastern Atlantic in 2005 to study the distribution of the trace elements Hg (mercury), Pb (lead), Cd (cadmium), Cu (copper), Ni (nickel), Zn (zinc), Co (cobalt), Mn (manganese), Fe (iron), and Al (aluminium). With the exception of Hg, results were compared to earlier datasets from 1989 to 1990. The particulate fraction averaged over the transect was calculated to be 49% for Cd, 23% for Mn and 50% for Fe indicating a release of these TEI's (trace elements and their isotopes) from a leachable SPM fraction in the stored and acidified samples.Total Pb concentrations ranged between 5 and 20 pmol kg^? 1 in 2005 with highest values in the ITCZ (intertropical convergence zone). In 1989 Pb concentrations were twice as high in the region of the ITCZ, while by a factor of 10–15 higher values were obtained in the North Atlantic.Total Cd and Co are dominated, by different seasonal upwelling regimes (Equatorial upwelling, Guinea Dome, Angola Dome).Total Cu, Ni, Fe, Mn and Al show nearly identical concentrations in 1990 and 2005. For total manganese and aluminium strong maxima (3–4 nmol kg^? 1 and 55 nmol kg^? 1 respectively) are observed between 23°N and 0°, while the Fe maximum (6–9 nmol kg^? 1) is located at 7°N. Total Hg concentrations ranged between 0.5 and 4.5 pmol kg^? 1.     

Chemical and mineralogical composition of marine sediments, and relation to their source and transport, Gulf of Carpentaria, Northern Australia

The Gulf of Carpentaria is an epicontinental sea, deeply indented in the north of the Australian continent. A selection of 100 samples of the surficial marine sediments collected on a regional grid were analysed for major chemical elements and mineral phases using wet chemistry, X-ray diffraction, optical and electronic microscopy.The surficial sediments of the Gulf are highly heterogenous and consist of both young and relict mineral and carbonate components. The terrigenous fraction is fluvial in origin and consists mainly of quartz (16–68%), minor feldspars (0–9%) and traces of siderite. The clay species determined include kaolinite, mixed layers of smectite–illite and illite; clays range up to 15% and do not present a clear pattern of distribution. Biologically productive areas of the Gulf, mainly in shallower parts, supply the carbonate component of the sediment. The carbonate material is comprised of aragonite (7–30%), low-Mg (5–30%) and high-Mg calcite (7–28%), and has variable degrees of alteration caused by sediment transport and/or diagenesis. Such processes are partly reflected in the regional distribution of mineral and chemical components throughout the Gulf. The interpretation of the data set was further refined by cluster analysis (Ward's method), which separated eight clusters (provinces) of sedimentary material. The eastern side appears to be the main source of both terrigenous and carbonate sediment, which is inferred to be transported clockwise. During this dispersion, physicochemical and mineralogical changes take place; the sediments become finer grained and characterised by more stable species of carbonates. As a consequence, the center and the northwest sections are clay-rich and contain dominantly low-Mg calcite.Ooids are relict components that have been identified in areas in which they were not mentioned by previous studies, notably in the southeast. These carbonate particles consist of concentric layers of aragonite deposited around a nucleus of angular quartz, most likely of fluvial origin.This study indicates a complex history over a short time frame with sediment supply, biological production and current patterns being the main factors that control the sediment character and its regional distribution within the Gulf.

Congress,reform, and oceans policy

Congress has not been able to pass comprehensive oceans policy legislation in recent years. Nonetheless, significant individual oceans policy measures have been enacted. These are reviewed in the article. A Joint Committee on the Organization of Congress has been established to recommend reforms in how Congress conducts its business, including proposals for committee restructuring. These proposals could affect how Congress examines oceans policy issues, but it is unlikely that these reforms will make it easier to pass comprehensive oceans policy legislation. For this to happen, well‐organized constituencies have to demonstrate support for this legislation, which has not happened to date.
