“…Inter-basin spread to the Caspian Sea occurred in the late 1990s, reportedly due to the release of ballast water from the Black-Azov basin (Ivanov et al 2000). In 2006 it was found in the Baltic and North seas (Faasse and Bayha 2006;Javidpour et al 2006Javidpour et al , 2009Boersma et al 2007). In 2009, M. leidyi was reported along the French coast of the Mediterranean Sea, in the northern Adriatic Sea (Shiganova and Malej 2009), in the southern Levantine Sea (Galil et al 2009), and in the western Mediterranean (Boero et al 2009;Fuentes et al 2009).…”

The introduction and spread of non-indigenous species (NIS) in marine ecosystems accelerated during the twentieth century owing to human activities, notably international shipping. Genetic analysis has proven useful in understanding the invasion history and dynamics of colonizing NIS and identifying their source population(s). Here we investigated sequence variation in the nuclear ribosomal Internal Transcribed Spacer region of the ctenophore Mnemiopsis leidyi, a species considered one of the most invasive globally. We surveyed four populations from the native distribution range along the Atlantic coasts of the United States and South America, as well as six populations in the introduced range from the Black, Azov, Caspian and Baltic seas. Allelic and nucleotide diversity of introduced populations were comparable to those of native populations from which they were likely drawn. Introduced populations typically exhibited lower genetic differentiation (F ST = -0.014-0.421) than native populations (F ST = 0.324-0.688). Population genetic analyses supported the invasion of Eurasia from at least two different pathways, the first from the Gulf of Mexico (e.g., Tampa Bay) to the Black Sea and thence to the Caspian Sea, the second from the northern part of the native distribution range (e.g., Narragansett Bay) to the Baltic Sea. The relatively high genetic diversity observed in introduced populations is consistent with large inocula and/or multiple invasions, both of which are possible given ballast water transport and the extensive native distribution of the ctenophore in the Atlantic Ocean.

“…According to longterm data, the highest density of M. leidyi is observed during warm months in both introduced regions (Black Sea, Caspian Sea, Baltic Sea) and native waters (e.g. Narragansett Bay and Chesapeake Bay in NW Atlantic) (Shiganova 1998;Purcell et al 2001;Sullivan et al 2001;Kideys et al 2005aKideys et al , b, 2008Roohi et al 2003Roohi et al , 2008aJavidpour et al 2009). This shows the importance of warm temperature for population explosions.…”

“…During the deployment a variation in water height of ±0.2 m was observed, attributed to winds and pressure gradients over the Baltic Sea. A residence time of a few days has been reported for waters in Kiel Fjord during periods with strong winds (Javidpour et al, 2009). The major source of freshwater input is rainwater from Kiel and the surrounding areas, which drains into the fjord, and the Schwentine River, located at the eastern shore of the inner Kiel Fjord.…”

Evaluation of a Ferrozine Based Autonomous in Situ Lab-on-Chip Analyzer for Dissolved Iron Species in Coastal Waters

et al. 2017

The trace metal iron (Fe) is an essential micronutrient for phytoplankton growth and limits, or co-limits primary production across much of the world's surface ocean. Iron is a redox sensitive element, with Fe(II) and Fe(III) co-existing in natural waters. Whilst Fe(II) is the most soluble form, it is also transient with rapid oxidation rates in oxic seawater. Measurements of Fe(II) are therefore preferably undertaken in situ. For this purpose an autonomous wet chemical analyzer based on lab-on-chip technology was developed for the in situ determination of the concentration of dissolved (<0.45 µm) Fe species (Fe(II) and labile Fe) suitable for deployments in a wide range of aquatic environments. The spectrophotometric approach utilizes a buffered ferrozine solution and a ferrozine/ascorbic acid mixture for Fe(II) and labile Fe(III) analyses, respectively. Diffusive mixing, color development and spectrophotometric detection take place in three separate flow cells with different lengths such that the analyzer can measure a broad concentration range from low nM to several µM of Fe, depending on the desired application. A detection limit of 1.9 nM Fe was found. The microfluidic analyzer was tested in situ for nine days in shallow waters in the Kiel Fjord (Germany) along with other sensors as a part of the SenseOCEAN EU-project. The analyzer's performance under natural conditions was assessed with discrete samples collected and processed according to GEOTRACES protocol [acidified to pH < 2 and analyzed via inductively coupled plasma mass spectrometry (ICP-MS)]. The mechanical performance of the analyzer over the nine day period was good (consistent high precision of Fe(II) and Fe(III) standards with a standard deviation of 2.7% (n = 214) and 1.9% (n = 217), respectively, and successful completion of every programmed data point). However, total dissolved Fe was consistently low compared to ICP-MS data. Recoveries between 16 and 75% were observed, indicating that the analyzer does not measure a significant fraction of natural dissolved Fe species in coastal seawater. It is suggested that an acidification step would be necessary in order to ensure that the analyzer derived total dissolved Fe concentration is reproducible and consistent with discrete values.
