Coastal eutrophication, land use changes and Ceratium furca (Dinophyceae) blooms in Pago Pago Harbor, American Samoa 2007-2009

The bloom forming dinoflagellate, Ceratium furca, has been linked with coastal eutrophication worldwide in tropical and subtropical locations. During the summer of 2007, an unusual 6-month long bloom of C. furca was observed in Pago Pago Harbor, Tutuila Island, American Samoa. Incidents of dinoflagellate blooms in this area have not been previously reported. The bloom was first reported in May and dissipated in November 2007. In February-March 2009, a similar C. furca bloom was observed. During both blooms, no fish mortality events were reported. Maximum cell counts were observed on September 20, 2007 at 9 200 cell/mL. At this time, total nitrogen was measured at 1.2 mg/L while total phosphate was below detection limits. Changes in land use practices may have been the primary driver of these blooms. Intense fertilization of athletic fields coupled with ineffective management strategies is hypothesized to have a direct link to the increase in nutrients found in the Pago Pago Harbor and may have been the trigger for the initialization of these blooms. During 2008, the fields were not used due to an infestation of the fire ant, Solenopsis geminata. Once controlled, the fields were opened again in 2009 and fertilizers were applied in January, a month before the bloom was observed.

Recent emergence and outbreak of rotavirus gastroenteritis in Samoa:A scoping review of risk factors,containment measures and public health preparedness

Diarrheal diseases have been known to cause death in many children below the age of five years,and rotavirus infection represents a major health problem in the world today,particularly in developing countries.The recent outbreak of rotavirus gastroenteritis in Samoa led to the introduction of her debut national immunization program on rotavirus vaccination for infants.Despite the introduction of anti-viral and anti-emetic drugs as of the containment approaches towards the virus,risk factors,preventive measures and public health preparedness against rotavirus infection are poorly understood in Samoa.This review aims to use available evidence on rotavirus literature to elucidate and map preventive strategies for the recently emerged rotavirus infections in Samoa.We conducted a search strategy using online medical literature databases and retrieval systems.A designated set of keywords such as rotavirus,gastroenteritis,outbreak,risk factors,containment measures,vaccination and Samoa were inserted in electronic databases to retrieve articles.The databases included Pub Med,Google Scholar,MEDLINE,Scinapse,and EBSCO host.Findings from this review addressed the impact of rotavirus infection,associated threats and other preventive measures.Introducing useful health frameworks in pursuing possible methods such as improved water quality,exclusive breast feeding,improved laboratory diagnostics and outbreak surveillance,may be essential in addressing alternate approaches towards containment of the disease in Samoa and other Pacific Island Countries and Territories.

Preliminary Assessment of Heavy Metals in Soil along the Vaisigano River in Samoa

The contamination of heavy metals in various environmental matrices is a major concern to many researchers and requires attention due to their detrimental impacts on the environment and humans as well. This research was carried out to investigate heavy metal levels in soils of some selected sites along the Vaisigano river in Upolu, Samoa. The soil samples were also analysed for physicochemical parameters such as pH, Electrical Conductivity, Moisture Factor, Cation Exchange Capacity (CEC), Organic Carbon, Nitrogen, Phosphorus, and Soil texture. The mean concentrations of heavy metals at the Lelata site were 0.19 ± 0.05 mg/kg (Pb), 0.37 ± 0.45 mg/kg (Mn), 0.15 ± 0.02 mg/kg (Zn) and 0.56 ± 0.42 mg/kg (Cu). The mean concentrations of heavy metals at the Alaoa site were 0.13 ± 0.03 mg/kg (Pb), 0.42 ± 0.51 mg/kg (Mn), 0.16 ± 0.03 mg/kg (Zn) and 0.45 ± 0.43 mg/kg (Cu). The heavy metal concentrations from both sites were lower than the permissible levels given by the World Health Organization (WHO). The Geo-accumulation pollution index (I(geo)) of heavy metals in the Lelata site was Cu > Mn > Pb > Zn and from the Alaoa site was Cu > Pb > Zn > Mn.

Chemical Composition of Rainwater at Selected Sites on Upolu Island, Samoa

The study involved analysis of rainwater samples at four sites on Upolu Island, Samoa from November 2019 to April 2020. A total of 48 rainwater samples were analysed in order to determine the major cations (Na+, Mg2+, Ca2+, K+) and anions (Cl-, , ) in wet precipitation from the four sites. The average pH of the rainwater was 6.89, perhaps due to neutralization. Only 50% of the rain samples had a pH above 5.6. This shows strong inputs of alkaline species to rainwater samples in some sites. The average pH of samples higher than 5.6 is due to high loadings of sodium ions. The rainwater samples are dominated by Na+, Ca2+, Mg2+, Cl- and . The principal cations and anions, in decreasing order, are Na+ > Mg2+ > Ca2+ > K+ and Cl- > > . The correlation study and the comparison of major ion composition with other sites revealed that rainwater ion composition is strongly influenced by marine sources rather than anthropogenic and terrestrial sources.

Deformations of Land,Sea and Gravity Levels by the 2009 Samoa Earthquake

The Samoa Islands were struck by the September 2009 earthquake of Mw 8.1. We study the effect on the land level by means of GPS monitoring and on ocean level by tide-gauge records. This allows us to present a new picture of the interaction of crustal movements, gravitational adjustment and sea level changes. The land level exhibits a co-seismic uplift followed by a post-seismic crustal subsidence. The ocean level records a fall, significantly larger than the uplift and delayed by several months, followed by a significant rise, by far exceeding the crustal subsidence and delayed by several months. This indicates a significant contribution from changes in gravity (geoidal eustasy), besides relative sea level changes due to crustal movements. High amplitude, and high frequency changes in tidal range provide evidence of changes in gravity and geoidal eustasy.

中国对萨摩亚援助述论

对外援助是中国和平外交的主要内容,也是中国主动承担大国义务、显示大国责任的重要举措。自1975年中萨建交以来,中国政府通过全额援建、优惠贷款、技术合作、人力资源援助等形式对萨摩亚进行了多领域、多渠道援助,包括基础设施建设、选派医疗队、农业技术支持、派遣理科教师以及紧急人道主义援助等,为萨摩亚的经济建设、社会发展、民众生活提供了有力支持,收到了良好成效。但从目前看来,对萨援助还存在短期培训项目密集重复、室内配套物资没有充分考虑当地实际、后期维护没有及时跟进等问题,需要进一步改进。

萨摩亚体育生活方式考察

运用体育人类学理论与方法,从体质和文化两方面入手对萨摩亚的体育生活方式进行实地调查,对一个既现代又传统的南太平洋岛国的体育生活进行较全面解析。结果显示:在体育文化多样性进程中,萨摩亚人能根据人和体育的自然性和社会性,因地制宜、因陋就简开展各种体育活动;萨摩亚人的心理顺应性,使其能够比较平和地接受殖民时期宗主国的文化对其体育产生的深远影响,形成了今天将传统体育、特色体育项目和现代体育融合起来的体育生活方式;而作为对国民体质健康的深切关照,萨摩亚政府高层带头参与体育活动与赛事,推崇现代竞技体育项目,将体育营造成一种大众的生活方式;同时积极参与和承办国际赛事,又体现了一个摆脱殖民的独立民族对自身体育文化提升的诉求,彰显萨摩亚的独立自主发展的国家形象。

清驻德属西萨摩亚领事林润钊对华工的保护

清驻德属西萨摩亚领事的派设,相比其它国家为时较晚,但华工遭受的凌辱虐待并不稍显逊色。广东洋务委员林润钊因精通英文、谙练交涉、熟悉情形而被派充驻萨首任领事,可谓人地相宜,才尽其用。林润钊任内恪尽职守,不辱使命,在内外臣工和旅萨华工的积极配合下,通过同萨督反复谈判,匡正诸多不利于华工的旧章苛例,华工的法律地位有所提高,工作待遇有所改善,尊严、权益得到一定程度的保障,实属晚清精明强干的外交良才。
