Autor: Yingxu Wu, Dorothee C. E. Bakker, Eric P. Achterberg, Amavi N. Silva, Daisy D. Pickup, Xiang Li, Sue Hartman, David Stappard, Di Qi, Toby Tyrrell

Publikováno v: Communications Earth & Environment, Vol 3, Iss 1, Pp 1-11 (2022)

Comparison of carbon dioxide and oxygen concentrations in ocean surface waters relative to saturation can be used to identify erroneous data collected by autonomous ocean platforms, suggests an analysis of data from multiple global datasets

History of carbonate ion concentration over the last 100 million years II: Revised calculations and new data

Autor: Richard E. Zeebe, Toby Tyrrell

Publikováno v: Geochimica et Cosmochimica Acta. 257:373-392

In an earlier contribution to this journal, we provided a reconstruction of seawater carbonate ion concentration over the last 100 million years (Tyrrell, T. and Zeebe, R.E., Geochim. Cosmoch. Acta, 68, 3521-3530, 2004; TZ04 hereafter). Since then, m

What drives the latitudinal gradient in open-ocean surface dissolved inorganic carbon concentration?

Previous work has not led to a clear understanding of the causes of spatial pattern in global surface ocean dissolved inorganic carbon (DIC), which generally increases polewards. Here, we revisit this question by investigating the drivers of observed

Chance played a role in determining whether Earth stayed habitable

Autor: Toby Tyrrell

Earth’s climate has remained continuously habitable throughout 3 or 4 billion years. This presents a puzzle (the ‘habitability problem’) because loss of habitability appears to have been more likely. Solar luminosity has increased by 30% over t

Latitudinal patterns in the concentrations of biologically utilised elements in the surface ocean

Autor: Toby Tyrrell, Daisy Pickup

Understanding of controls on the spatial distributions of chemical elements in the surface ocean has improved over time. Macronutrients were understood first, followed by dissolved inorganic carbon and alkalinity. Utilising data collected in the Atla

Spatial variations in silicate-to-nitrate ratios in Southern Ocean surface waters are controlled in the short term by physics rather than biology

Autor: Toby Tyrrell, Mark Christopher Moore, Adrian Martin, Alberto C. Naveira Garabato, Pieter Demuynck

Publikováno v: Biogeosciences (1726-4170) (Copernicus Gesellschaft Mbh), 2020-04, Vol. 17, N. 8, P. 2289-2314
Biogeosciences, Vol 17, Pp 2289-2314 (2020)

The nutrient composition (high in nitrate but low in silicate) of Subantarctic Mode Water (SAMW) forces diatom scarcity across much of the global surface ocean. This is because diatoms cannot grow without silicate. After formation and downwelling at

Analysis of longitudinal variations in North Pacific alkalinity to improve predictive algorithms

Autor: Toby Tyrrell, Claudia H. Fry, Eric P. Achterberg

Publikováno v: Global Biogeochemical Cycles. 30:1493-1508

The causes of natural variation in alkalinity in the North Pacific surface ocean need to be investigated to understand the carbon cycle and to improve predictive algorithms. We used GLODAPv2 to test hypotheses on the causes of three longitudinal phen

Preface: Field investigation of ocean acidification effects in northwest European seas

Autor: Eric P. Achterberg, Toby Tyrrell

Publikováno v: Biogeosciences (BG), 11 (24). pp. 7269-7274.
Biogeosciences, Vol 11, Iss 24, Pp 7269-7274 (2014)

The pH of the ocean is being lowered by its uptake of anthropogenic atmospheric carbon dioxide (CO2), produced as a result of combustion of fossil fuels and land use changes. This acidification is especially pronounced in the surface ocean, where the
