Relationship between surface chlorophyll and chlorophyll in the euphotic zone of the Gulf of California: possible application to estimate primary production with data obtained by remote sensors

open access: yesCiencias Marinas, 1993
The vertical distribution of pigments (chlorophyll a) in the study area showed maximum surface chlorophyll to the north of line 240, subsurface and deep chlorophyll maxima to the South of line 320 and both kinds of distribution between lines 240 and 320.

Estimates of the rates of mortality of yellowfin tuna in the Eastern Pacific Ocean derived from tagging experiments [PDF]

open access: yes, 1971
ENGLISH: Tag release and return data for the Baja California and Gulf of Guayaquil areas were selected for this study because substantial numbers of returns resulted from these releases and because the effects of emigration are small in these areas.

Toward Stable Multivalent Metal Batteries: Understanding the Interfacial Chemistry for Magnesium and Calcium Metal Anodes

open access: yesAdvanced Functional Materials, EarlyView.
Interphase chemistry governs the stability of multivalent metal batteries. We summarize state‐of‐the‐art developments in calcium and magnesium metal batteries by focusing on the correlation among electrolytes, interphase layers, and the electrochemical performance of corresponding metal anodes.
