“…One of these was developed to study hydrothermal vent-fluid chemistry (Battaglia et al 2004;Dable et al 2006), and uses a variety of modified components including a Control Development Inc. spectrometer. The other 785 nm system was developed to detect polyaromatic hydrocarbons in seawater (Schmidt et al 2004), and uses a custom surface-enhanced Raman spectroscopy probe and a Jobin Yvon spectrometer (Kronfeldt & Schmidt 1999). These choices between 532 and 785 nm excitation wavelength are worth reviewing.…”

“…In this method, Raman bands are used to identify species; Raman intensities are not used to infer concentration. In addition to being largely qualitative, deep-sea Raman applications to date have also focused on strong Raman scatterers such as CH 4 gas and hydrates (Hester et al 2007), or dissolved analytes that can be measured by surface-enhanced Raman scattering (Schmidt et al 2004). Even a short list of the most abundant hydrothermal minerals includes many that are weak Raman scatterers and share similar chemistries, and thus similar Raman spectra (figure 2; table 2).…”

“…Such an approach would greatly improve our understanding of (i) the chemical evolution of hydrothermal systems themselves, (ii) the structure and biogeochemical cycling within microbial mats, and (iii) the impact of hydrothermal venting upon global ocean chemistry. Sea-going Raman systems have been built (Battaglia et al 2004;Brewer et al 2004;Schmidt et al 2004) and deployed to manually analyse gases (White et al 2006a); synthetic and natural clathrate hydrates (Hester et al 2006(Hester et al , 2007; and minerals, fluids and bacterial mats at hydrothermal vents (White et al 2006b;White 2009). Laboratory testing has proven the ability to quantitatively, and autonomously distinguish many minerals typically found at deep-sea hydrothermal vents, even minerals with similar chemical compositions (figure 2; Breier et al 2009a).…”

In deep-sea hydrothermal environments, steep chemical and thermal gradients, rapid and turbulent mixing and biologic processes produce a multitude of diverse mineral phases and foster the growth of a variety of chemosynthetic micro-organisms. Many of these microbial species are associated with specific mineral phases, and the interaction of mineral and microbial processes are of only recently recognized importance in several areas of hydrothermal research. Many submarine hydrothermal mineral phases form during kinetically limited reactions and are either metastable or are only thermodynamically stable under in situ conditions. Laser Raman spectroscopy is well suited to mineral speciation measurements in the deep sea in many ways, and sea-going Raman systems have been built and used to make a variety of in situ measurements. However, the full potential of this technique for hydrothermal science has yet to be realized. In this focused review, we summarize both the need for in situ mineral speciation measurements in hydrothermal research and the development of sea-going Raman systems to date; we describe the rationale for further development of a small, low-cost sea-going Raman system optimized for mineral identification that incorporates a fluorescence-minimizing design; and we present three experimental applications that such a tool would enable.

Detecting marine hazardous substances and organisms: sensors for pollutants, toxins, and pathogens

Abstract. Marine environments are influenced by a wide diversity of anthropogenic and natural substances and organisms that may have adverse effects on human health and ecosystems. Real-time measurements of pollutants, toxins, and pathogens across a range of spatial scales are required to adequately monitor these hazards, manage the consequences, and to understand the processes governing their magnitude and distribution. Significant technological advancements have been made in recent years for the detection and analysis of such marine hazards. In particular, sensors deployed on a variety of mobile and fixed-point observing platforms provide a valuable means to assess hazards. In this review, we present state-of-the-art of sensor technology for the detection of harmful substances and organisms in the ocean. Sensors are classified by their adaptability to various platforms, addressing large, intermediate, or small areal scales. Current gaps and future demands are identified with an indication of the urgent need for new sensors to detect marine hazards at all scales in autonomous real-time mode. Progress in sensor technology is expected to depend on the development of small-scale sensor technologies with a high sensitivity and specificity towards target analytes or organisms. However, deployable systems must comply with platform requirements as these interconnect the three areal scales. Future developments will include the integration of existing methods into complex and operational sensing systems for a comprehensive strategy for long-term monitoring.Correspondence to: O. Zielinski (oliver.zielinski@imare.de)The combination of sensor techniques on all scales will remain crucial for the demand of large spatial and temporal coverage.

“…Other than optimizing the sizes, shapes and components of noble metallic nanoparticles (typically, silver or gold) [13][14][15][16][17][18], the design of ideal SERS substrate with the capability to extract target from complex matrix more efficient has become a commonly used way to improve the Raman signals [12,[19][20][21][22][23][24]. Conventional types of the solid SERS substrate, such as glass slide or silicon wafers [25,26], possess a rigid architecture resulting in low conformal contact with the sample surface and thus poor extraction ability.…”

In surface-enhanced Raman scattering (SERS), flexible substrate plays an important role in target molecular collection from various shape surfaces and increases the analytical sensitivity. In this study, silver nanoparticles (Ag NPs) were deposited on a non-woven fabric used as an SERS substrate by self-assembly, in situ growing or the self-assembly/in situ growing combination method. 4-Aminothiophenol was selected as a model molecular for the evaluation of the SERS performance using the substrates. The Ag NPs substrate prepared by self-assembly/ in situ growing method presented the best Raman enhancement effect and its enhancement factor was estimated as high as 3.5 9 10 6 . The substrate was applied to the determination of four pesticide residues on the surfaces of fruit samples through wipe sampling, and the results revealed the good reproducibility of SERS responses and high detection sensitivity. The prepared flexible substrate was simple to fabricate and environmentally friendly. It could be expected to be a useful tool in rapid on-site test of pesticide residues on fruit surfaces because of its high sensitivity, convenience and non-destructive characteristics.
