Oil Tankers

In the coastal regions of the North- and Baltic-Seas of Germany more collisions with oil tankers have occured since 1955. These collisions have been followed by extreme pollution of the sea and coastal areas. In the following report the possibility of computing in advance the time and place of the landing of sludge, the advantages and disadvantages of chemical and mechanical treatment for the removal of the oil, the natural influences on the decomposition of the oil and the differences between oil pollution on coasts with tides and on coasts without tides are explained and critizised. Coastal areas and beaches are in danger of being polluted by oil. One part is the uncontrolled disposal of waste oil causing permanent pollution, the other part is the result of collisions with vessels. This danger is most threatening on much frequented shipping routes and in limited and relatively small sea-areas and bays of low depth, as it is the case with the North-and Baltic-Seas in the North of Europe.

The callipodidan milliped, Sinocallipus simplipodicus Zhang, 1993, previously known only from a cave in Yunnan Province, China, is redescribed based on specimens from an epigean habitat in southern Laos, some 600 mi (960 km) south of the type locality. SEM photos of the gonopods, ovipositor, gnathochilarium, midbody exoskeleton, an ozopore, and legs are presented to supplement previously published line drawings; the cannula may be the “functional” element of the gonopod that inseminates females in this species. The Callipodida occupy nine disjunct areas globally, all exclusively in the Northern Hemisphere and most in the North Temperate Zone; there are three regions each in North America, Europe (including coastal regions along the southern Black and eastern Mediterranean seas that are technically part of Asia), and Asia proper. The southeast Asian fauna comprises three families -Sinocallipodidae, one genus and species (suborder Sinocallipodidea), and Schizopetalidae, one genus and species, and Paracortinidae, one genus, three subgenera, and seven species (both suborder Schizopetalidea). An unnamed clade may exist in the Diplopoda in which the gonopods arise solely from the 8th legs (an “8th gonopod clade”); it comprises seven orders: Callipodida, Polydesmida, Chordeumatida, Stemmiulida, Siphoniulida, Spirostreptida, and Epinannolenida. Two newly recognized characters that hold phylogenetic significance are (1) development of the gonopod from the 8th coxa alone (Chordeumatida) or from the coxa plus some telopodal articles (the other six orders), and (2) the presence (Callipodida, Polydesmida, and Stemmiulida) or absence (Chordeumatida, Spirostreptida, and Epinannolenida) of a cannula. These considerations lead to the hypothesis (Chordeumatida + (Callipodida + (Polydesmida + Stemmiulida))).

Mode Of Attachment

The fishes harbouring parasites of the genus Lernaeocera can be divided, according to the presence or absence of contact with the coastal waters, into ‘inshore’ and ‘offshore’ groups. According to literature, only L. branchialis occurs commonly on hosts in both groups. The difference between this and the remaining species of the genus is explained by the existence of two different species covered by the name L. branchialis. One of these species is parasitic on cod and whiting, the other on haddock. The two species have also different intermediate hosts (flounder and lemon sole respectively) and differ in morphology of the adult male and female and in the mode of attachment to the final host.Lernaeocera of whiting and cod is distributed mainly in the coastal area, while that from haddock extends over the whole of the North Sea. The former, but not the latter, is present outside the European continental shelf. All these differences lead to the conclusion that the two types represent two different species. The old name is retained for the parasite of cod and whiting. The parasite of haddock is the new species, to which the name Lernaeocera obtusa is given.

In this study, using Aerosol Robotic Network aerosol optical depth (AOD) products at three stations in the North China Plain (NCP)—a heavily polluted region in China—the AOD products from six satellite-borne radiometers: the Moderate Resolution Imagining Spectroradiometer (MODIS), the Multiangle Imaging Spectroradiometer (MISR), Ozone Mapping Imaging (OMI), the Visible Infrared Imaging Radiometer (VIIRS), the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS), and Polarization and Directionality of the Earth’s Reflectances (POLDER), were thoroughly validated, shedding new light on their advantages and disadvantages. The MODIS Deep Blue (DB) products provide more accurate retrievals than the MODIS Dark Target (DT) and other satellite products at the Beijing site (BJ,a megacity), with higher correlations with AERONET (R > 0.93), lower mean absolute bias (MB < 0.012), and higher percentages (>68%) falling within the expected error (EE). All MODIS DT and DB products perform better than the other satellite products at the Xianghe site (XH, a suburb). The MODIS/Aqua DT products at both 3-km and 10-km resolutions performed better than the other space-borne AOD products at the Xinglong site (XL, a rural area at the top of a mountain). MISR, VIIRS, and SeaWiFS tend to underestimate high AOD values and overestimate AOD values under very low AOD conditions in the NCP. Both OMI and POLDER significantly underestimate the AOD. In terms of data volume, MISR with the limited swath width of 380 km has less data volume than the other satellite sensors. MODIS products have the highest sampling rate, especially the MODIS DT and DB merged products, and can be used for various climate study and air-quality monitoring.

First Time

Data obtained from licenses of spearfishers and surveys conducted in 2004 and 2017 allowed for the analysis, for the first time, of the practice of spearfishing in the Madeira archipelago. Only a small percentage of the population practices spearfishing, mostly local young men. Most of them practice the activity with a partner throughout most of the year and along most of the island's coastal areas, although preferentially along the North and Southeast coast. Results show how, in recent years, despite the population of spearfishers decreasing, the abundance in the annual catch potentially increased, probably due to the higher investment of time in this activity. It has been observed that many fishers complement their catches with manual collecting of invertebrates. Overall, 40 teleost fishes and also 4 crustaceans and 8 molluscs were identified. The most frequently captured fish species were parrotfish and white seabream, while limpets were the most collected invertebrates in both selected periods.

Papilio Demoleus

We review the continuing and extensive spread of Papilio demoleus in south-eastern Turkey and in regions of Turkey and Syria adjacent to the north-eastern Mediterranean. Since the authors documented the arrival of this attractive but potentially destructive papilionid species at coastal areas of Syria in 2019, regular monitoring has confirmed successful overwintering there, as well as in Turkey. As previously indicated, P. demoleus is widely recognized as an invasive pest species in Citrus-growing areas of the world and hence its arrival is of potential economic importance to a region in which citrus is widely grown.

This study is focused on the alterations and typical features of the wind wave climate of the Black Sea’s coastal waters since 1979 till nowadays. Wind wave parameters were calculated by means of the 3rd-generation numerical spectral wind wave model SWAN, which is widely used on various spatial scales – both coastal waters and open seas. Data on wind speed and direction from the NCEP CFSR reanalysis were used as forcing. The computations were performed on an unstructured computational grid with cell size depending on the distance from the shoreline. Modeling results were applied to evaluate the main characteristics of the wind wave in various coastal areas of the sea.

Geology of Greenland Survey Bulletin, 183, 23-33. https://doi.org/10.34194/ggub.v183.5201 _______________ During a five week period in August–September 1998 the poorly known north-eastern part of the Palaeoproterozoic (c. 1800 Ma) Ketilidian orogen between Kangerluluk and Mogens Heinesen Fjord in South-East Greenland (Fig. 1) was investigated in continuation of recent geological research in other parts of the orogen. The north-eastern part of the orogen is remote from inhabited areas. It is mountainous and comprises a wide nunatak zone which can only be reached easily by helicopter. Furthermore, access to coastal areas by boat is difficult because many parts of the coast are prone to be ice-bound even during the summer months, due to wind- and current-driven movements of the sea ice.

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.
