Oceanic controls on the primary production of the northwest European continental shelf: model experiments under recent past conditions and a potential future scenario [PDF]

open access: yesBiogeosciences, 2012
In this paper we clearly demonstrate that changes in oceanic nutrients are a first order factor in determining changes in the primary production of the northwest European continental shelf on time scales of 5–10 yr.

Distribution of Calanus spp. as determined using a genetic identification system

open access: yesScientia Marina, 2004
The morphological similarity of Calanus species necessitates that the only unambiguous way of discriminating between the different species at any developmental stage is with molecular tools.

Systeme zur mechanischen und mechanisch-chemischen Unkrautregulierung in Zuckerrüben (Beta vulgaris subsp. vulgaris) – Versuche in Niedersachsen

open access: yesJulius-Kühn-Archiv, 2020
Im Ökolandbau wird seit einigen Jahren die Zuckerrübe wieder im Vertragsanbau von Nord- und Südzucker angeboten. Bei Nordzucker nimmt die Anbaufläche von Biozuckerrüben stetig zu.

Effects of elevated CO2 and temperature on phytoplankton community biomass, species composition and photosynthesis during an experimentally induced autumn bloom in the western English Channel [PDF]

open access: yesBiogeosciences, 2018
The combined effects of elevated pCO2 and temperature were investigated during an experimentally induced autumn phytoplankton bloom in vitro sampled from the western English Channel (WEC).

A 40-year global data set of visible-channel remote-sensing reflectances and coccolithophore bloom occurrence derived from the Advanced Very High Resolution Radiometer catalogue [PDF]

open access: yesEarth System Science Data, 2018
A consistently calibrated 40-year-long data set of visible-channel remote-sensing reflectance has been derived from the Advanced Very High Resolution Radiometer (AVHRR) sensor global time series.

Surface heat fluxes and ecosystem function in the Cretan Sea (eastern Mediterranean): a modelling study [PDF]

open access: yesAnnales Geophysicae, 2003
As a component of the Mediterranean Forecast System Pilot Project, a data buoy was deployed in the Cretan Sea. A 1-D ecosystem model of the site has been used to investigate the role of surface heat fluxes in determining modelled ecosystem ...

Altered lipid accumulation in Nannochloropsis salina CCAP849/3 following EMS and UV induced mutagenesis

open access: yesBiotechnology Reports, 2015
Microalgae have potential as a chemical feed stock in a range of industrial applications. Nannochloropsis salina was subject to EMS mutagenesis and the highest lipid containing cells selected using fluorescence-activated cell sorting.

Evidence for the effects of decommissioning man-made structures on marine ecosystems globally: a systematic map

open access: yesEnvironmental Evidence, 2022
Background Many marine man-made structures (MMS), such as oil and gas platforms or offshore wind turbines, are nearing their ‘end-of-life’ and require decommissioning.

Consistency between Satellite Ocean Colour Products under High Coloured Dissolved Organic Matter Absorption in the Baltic Sea

open access: yesRemote Sensing, 2021
Ocean colour (OC) remote sensing is an important tool for monitoring phytoplankton in the global ocean. In optically complex waters such as the Baltic Sea, relatively efficient light absorption by substances other than phytoplankton increases product ...

Modulation of Polar Lipid Profiles in Chlorella sp. in Response to Nutrient Limitation

open access: yesMetabolites, 2019
We evaluate the effects of nutrient limitation on cellular composition of polar lipid classes/species in Chlorella sp. using modern polar lipidomic profiling methods (liquid chromatography⁻tandem mass spectrometry; LC-MS/MS).
