| Major changes are occurring across the North Atlantic climate system, including in the atmosphere, ocean and cryosphere, and many observed changes are unprecedented in instrumental records. As the changes in the North Atlantic directly affect the climate and air quality of the surrounding continents, it is important to fully understand how and why the changes are taking place, not least to predict how the region will change in the future. To this end, this article characterizes the recent observed changes in the North Atlantic region, especially in the period 2005–2016, across many different aspects of the system including: atmospheric circulation; atmospheric composition; clouds and aerosols; ocean circulation and properties; and the cryosphere. Recent... |

| The Global Ocean Data Assimilation Experiment (GODAE [http://www.godae.org]) has spanned a decade of rapid technological development. The ever-increasing volume and diversity of oceanographic data produced by in situ instruments, remote-sensing platforms, and computer simulations have driven the development of a number of innovative technologies that are essential for connecting scientists with the data that they need. This paper gives an overview of the technologies that have been developed and applied in the course of GODAE, which now provides users of oceanographic data with the capability to discover, evaluate, visualize, download, and analyze data from all over the world. The key to this capability is the ability to reduce the inherent complexity of... |

| This DAC cookbook is to include instructions for the DACs on how to calculate different variables for the Argo profile files. This is especially true for some of the additional sensors that are being added to Argo floats. The extra variables increase the complexity of the profile file and extra instructions may be necessary, depending on float and sensor type. It is separate from other data manuals because users do not need to understand all these details, but that it is important that all DACs to be calculating the variables in the same manner. There are instructions in this cookbook that apply to all floats and some that apply to only certain float types. Look through the table of contents for the specific float types included. |

| More than 90% of the heat energy accumulation in the climate system between 1971 and the present has been in the ocean. Thus, the ocean plays a crucial role in determining the climate of the planet. Observing the oceans is problematic even under the most favourable of conditions. Historically, shipboard ocean sampling has left vast expanses, particularly in the Southern Ocean, unobserved for long periods of time. Within the past 15 years, with the advent of the global Argo array of pro ling oats, it has become possible to sample the upper 2,000 m of the ocean globally and uniformly in space and time. The primary goal of Argo is to create a systematic global network of pro ling oats that can be integrated with other elements of the Global Ocean Observing... |

| Recent technological advancements have led to the development of 4 new Argo models capable of reaching the deep and abyssal oceans: Deep Arvor and the Deep NINJA, with a pressure limit of 4000 dbar and the Deep SOLO and Deep APEX, with a pressure limit of 6000 dbar. Over the past 3 years, these new deep Argo floats have been tested in a number of regional pilot arrays. The international 2nd Deep Argo Workshop has been held at CSIRO in Hobart, Tasmania on May 13-15, 2019 in order to advance the global implementation of a Deep Argo array by: • Presenting new Deep-Argo-based scientific results • Reviewing the objectives of the Deep Argo Program • Describing the Deep Argo float mission in support of Deep Argo’s scientific objectives • Confirming Deep Argo... |

| The Argo Program has been implemented and sustained for almost two decades, as a global array of about 4000 profiling floats. Argo provides continuous observations of ocean temperature and salinity versus pressure, from the sea surface to 2000 dbar. The successful installation of the Argo array and its innovative data management system arose opportunistically from the combination of great scientific need and technological innovation. Through the data system, Argo provides fundamental physical observations with broad societally-valuable applications, built on the cost-efficient and robust technologies of autonomous profiling floats. Following recent advances in platform and sensor technologies, even greater opportunity exists now than 20 years ago to (i)... |

| The Argo network of autonomous profiling floats will provide the first global views of the time-varying temperature (T) and salinity (S) fields of the upper ocean. Argo will serve a broad community of scientific and operational users, with objectives falling into several categories. It will provide a quantitative description of the evolving physical state of the upper ocean and the patterns of ocean climate variability, including heat and freshwater storage and transport. The data will enhance the value of the Jason altimeter through measurement of the subsurface vertical structure of T and S, plus reference velocity, with sufficient coverage and resolution for interpreting altimetric sea surface height variability. Argo data will be used for initializing... |
