Global perspectives on observing ocean boundary current systems

…, R Hummels, S Ito, M Krug, F Lacan… - Frontiers in Marine …, 2019 - frontiersin.org
Ocean boundary current systems are key components of the climate system, are home to
highly productive ecosystems, and have numerous societal impacts. Establishment of a global …

Neodymium isotopes as a new tool for quantifying exchange fluxes at the continent–ocean interface

F Lacan, C Jeandel - Earth and Planetary Science Letters, 2005 - Elsevier
Continental margins are, via river sediment discharges, the major source of a number of
elements to the ocean. They are also, for several reactive elements, sites of preferential removal …

Bioactive trace metals and their isotopes as paleoproductivity proxies: An assessment using GEOTRACES‐era data

…, SJG Galer, SL Jaccard, F Lacan… - Global …, 2021 - Wiley Online Library
… terms represent quantities and f is unitless. (It follows that the fraction of nutrient consumed
by phytoplankton equals 1−f.) In systems where most nutrients are consumed, f will be close …

Isotopic Nd compositions and concentrations of the lithogenic inputs into the ocean: A compilation, with an emphasis on the margins

C Jeandel, T Arsouze, F Lacan, P Téchiné, JC Dutay - Chemical Geology, 2007 - Elsevier
An extensive compilation of published Nd isotopic values has been made in order to establish
a database and a map of the isotopic composition of Nd of the world coasts. Both the …

Tracing Papua New Guinea imprint on the central Equatorial Pacific Ocean using neodymium isotopic compositions and Rare Earth Element patterns

F Lacan, C Jeandel - Earth and Planetary Science Letters, 2001 - Elsevier
The Nd isotopic composition (IC) and Rare Earth patterns of hydrodynamic structures of the
Equatorial Pacific Ocean were characterized along 140W. The Nd IC of Antarctic …

Reconstructing the Nd oceanic cycle using a coupled dynamical–biogeochemical model

T Arsouze, JC Dutay, F Lacan, C Jeandel - Biogeosciences, 2009 - bg.copernicus.org
The decoupled behaviour observed between Nd isotopic composition (Nd IC, also referred
as ε Nd ) and Nd concentration cycles has led to the notion of a "Nd paradox". While ε Nd …
