Use of Ra isotopes to deduce rapid transfer of sediment-derived inputs off Kerguelen [PDF]
Biogeosciences, 2015 The Southern Ocean is known to be the largest high-nutrient, low-chlorophyll (HNLC) region of the global ocean due to iron limitation. However, a large phytoplankton bloom develops annually downstream of the Kerguelen Islands, a bloom which is sustained ...

Volcanic ash as fertiliser for the surface ocean [PDF]
Atmospheric Chemistry and Physics, 2010 Iron is a key limiting micro-nutrient for marine primary productivity. It can be supplied to the ocean by atmospheric dust deposition. Volcanic ash deposition into the ocean represents another external and so far largely neglected source of iron.

Unveiling the Si cycle using isotopes in an iron-fertilized zone of the Southern Ocean: from mixed-layer supply to export [PDF]
Biogeosciences, 2016 A massive diatom bloom forms annually in the surface waters of the naturally iron-fertilized Kerguelen Plateau (Southern Ocean). In this study, silicon isotopic signatures (δ30Si) of silicic acid (DSi) and suspended biogenic silica (BSi) were ...

Fully pipelined bloom filter architecture [PDF]
, 2008 Recently, we proposed a two-stage pipelined Bloom filter architecture to save power for network security applications. In this letter, we generalize the pipelined Bloom filter architecture to k-stage and show that significant power savings can be ...

Low-power bloom filter architecture for deep packet inspection [PDF]
, 2006 Bloom filters are frequently used to identify malicious content like viruses in high speed networks. However, architectures proposed to implement bloom filters are not power efficient.
